The framing nailer in the pack linked earlier is the DCN692. On an older version of this nailer I was told to stay well clear.
As the firing mechanism fell to bits after sustained use.
You may have been told that, but it isn't first hand experience, and when DW brought their cordless first fix nailers out I suspect that Paslode possibly ran a negative campaign against them judging from the amount of "knowledgeable" negative comments on the 'net at the time after a very short period of use. Despite which I wrote a user review over on UHM giving the what I considered to be a truer picture. The DW guns also have quite a few advantages over Paslode's offerings, with jams being particularly easy to clear
The real answer is that, yes, DW are now on the DCN692 Type 3, which is stronger than the original, but that Type 1 guns are capable of quite long life (mine is about 4 years old and still in regular trade use - total spares to date have been two drive pins) but unlike Paslodes (or other gas guns - I also have a Senco GT90CH and a Rawl WW90CH) the DW takes a heck of a lot less maintenance (no gas or igniters or mucky oil, for example, and the battery contacts don't go black from arcing, either). What I will say is that they aren't the right gun to take onto a flooring job, you know, the type of job where you need to pound 150 to 200 75mm ring nails into sheets of plywood for hour after hour - but then neither is a Paslode gas nailer, because the IM350 isn't the most dependable of tools, judging from the five we have on the current job where there are always at least two out of commission or being repaired - and they all have a tendency to overheat and seize (based on no less than 4 jobs over the last 3 years where we've had new guns supplied by the contractor). Give me the old (defunct) IM90 any day! Oh, and in any case, the HAVS (hand arm vibration) rating on IM350s means that you'll do yourself physical damage if you repeatedly use them for more than about 2-1/2 hours a day. If you are talking about sustained use, the only safe and reliable option is pneumatic, and the best guns for that are probably Makita, Hitachi/Hikoki, Max and Senco. But for DIY use, we aren't talking that level of use, surely?
From my own experience for what the OP is looking to do by way of framing the DCN692 is more than man enough, if perhaps a tad heavy. If I were looking for lighter gun and was willing to go gas, I'd not considerthe Paslode - instead I'd look at either the Rawl WW90CH gas nailer (or the Senco GT90CH - they are the same gun in effect) or the Hitachi/Hikoki gas nailer (which was designed by the guy who originally designed the Paslode nailers).
If I was going down the route of a cordless-gasless framing nailer two choices come to mind..
1 - Hikoki NR1890DC
Maybe the OP would like to take look at
this mini review from Roger Bizby in which he compares the DW and Hitachi (Hikoki) offerings side by side?
As to the Milwaukee, it isn't yet available in the UK (although it is just out in the USA), but the nitrogen spring mechanism may well be an issue. Senco tried this idea with their 2nd fix Fusion nailers a few years back and they got a bit of a flakey reputation, with some having problems of low life of the nitrogen cylinder (they lose pressure over time and all need replacing periodically - which is expensive - some of the early ones had a very short life). The fact is, though, that Milwaukee isn't a company with any reputation in the nailer field and their first generation 2nd fix nailers were riven with problems. That means I'd probably trust their 2nd gen 2nd fix guns which will be here next year (after all, they've ironed out all the bugs, haven't they?), but I think I'll let others potentially burn their fingers on the 1st fix gun
For anyone else reading this who is unfamiliar with 1st fix nailers, all these guns use 30 to 34 degree paper collated clipped head or offset full head nails which are interchangeable between different brands of gun, so if you buy a Hitachi/Hikoki or whatever there's no need to buy their nails - I'd just avoid Champion nails because every time I've had them they gunked up the gun with oil
