A lot of the 'regulars' seem to be avoiding this thread as a waste of time, which it probably is, but I have to stand up for Floyd.
I've been using lo-pro bridges for about 10 years now. I play hard - my picking is hard, my fretting is hard. I'm not shy with the bar. Most of my gigs have an average of 3 hours playing time.
It's very very rare that I need to tune the guitar during a gig. If anything, my high-E string might drop a little, other than that it stays in tune - even gig to gig - a lot of times i show up after not having played for a few days and the damn thing is still in tune.
My ears are super-sensitive to pitch and out-of-tune guitars - I can tell when a keyboard is tuned to A442 instead of A440 byhearing one note. If all lo-pro bridges were as awful as you say yours is, I wouldn't still be playing on them. i doubt anybody would.
Your Jem is F*d up. Try another one, rather than having the one you have fixed (if you have indeed had it set up professionally). If a different one behaves the same way, by all means, go buy the YJM strat. Enjoy.
