They are probably all more than adequate for 8x10, but many that have meters may be a bit erratic, and/or run into the mercury battery problem. I have a Yashica MAT 124g, which I believe was their last TLR model. It's early 1980 vintage, thus pretty old. I have a battery adapter to try a silver oxide cell in it, but at the moment there is what may be a dirty contact problem in the switch that enables the meter when the hood is opened. I plan to get in there and look around one of these days, but meanwhile a Gossen Digisix solves my problem.

Just wanted to toss that out, as a small separate meter would leave you ready for any (or multiple!) camera(s) and might be better, or at least not a major deciding factor.
