Most people use either the Mono, or the DFP, both from Logitech, and they are considered the best for "bang-per-buck", unfortunately the pedals do tend to have a few problems.
Hmm Mono.. too much Linux perhaps? Surely you mean Momo
I use a MOMO Racing and haven't had any problems with the wheel or pedals so far, if possible go for a later revision, I think they're supposed to last longer or something.
IMHO the microsoft sidewinder FF USB is a great wheel too. got a used one for $35 and used it hundreds if not thousands of hours since. It's always 100% calibrated, very easy to attach/remove from the table and the ergonomics are fine for me.
The only potential issue with this wheel is that the built-in windows XP (and win2k too?) driver doesn't support separate axis for gas/breaks. So you can install a win98 driver which works fine on XP too for most ppl, but there's a warning on tom's hardware that it may crash the PC. never happened to me though and I like this wheel very much.
