Potterton Suprima HE

Have read on here lots of comments on the poor reliability of the Suprima L due to PCB failures etc. The design of this boiler puts all the electrics right next to the heat exchanger which may not have helped matters. The current Suprima HE looks to be a better design with the electricals moved to the bottom of the rack like the old Netaheat. Is the HE a better more reliable boiler than the L or should I steer clear ? Whats a good reliable alternative that will produce around 23Kw.
Thanks for your comments.

many would and will disagree but i think there is a fag paper difference between modern boilers in the reliability stakes, the suprima is probably as good as any

got loads round my manor, and have had to go out to VERY few.....
