I dont know why this has to devolve into a discussion about the posters motivations or 4x5 vs 8x10 or digital vs. film..
The guy asked a general question about a camera and indicated that it is with their budget. Why not just stay silent if you dont have anything pertinent to say?
-And if someone wants to buy new, we should be applauding them because they are keeping the manufacturers in business.
Regarding the chamonix.. I cannot comment on the 8x10 but I have handled 4x5's and they seem better built than my Shen-Hao. The focus knobs are larger (on the 4x5 at least).
The rear focus knob is a really nice feature (otherwise you have to reach around your camera to focus). It looks like the newer 8x10 has a bail back which really helps keep your camera from getting out of alighnment when inserting a film holder.
Well good luck on your purchase! Return back here for advice anytime!
