A couple of years ago I purchased the following Roughneck foam gun (£30).
www.toolstation.com
It has some PTFE fittings (needle and canister holder) but not as many as the more expensive version.
I went to use it today. No foam would come out, the canister has been connected for a few months and feels like it was about 60% full. I had a new canister and fitted it (assuming that the propellant from the old one had leaked). The new one wouldn't work either. The gun pin retracted with no problems.
I tried running gun cleaner through it, again, no luck.
I then opted to dismantle the gun to clean the components. Still no luck. I was using a decent Bahco adjustable spanner. Nothing would turn. I then used a small screwdriver to push down the ball bearing. All was good.
I am glad that it worked but I don't understand why I could not dismantle any of the components. It looks like it has been designed to break it down.
Assuming that it continues to function I will stick with it, but if it has a terminal failure, I would be willing to jump up to £50-60. Recommendations from professionals that use foam guns day in day out would would be appreciated (bearing in mind that I do not use them in day in day out) .
