liteon 18a1/20a1 series - excellent scanner; reads borderline discs quite well; good burner; liteon provides firmware updates for quite a long time (at least in the past they did, don't really see anything that would change that); has some firmware bugs though (I hope some issues I've had are f/w related and not h/w related)
pioneer 111 good burner; many crossflashing options
LG h42n good burner
if you can find a benq 165x they are pretty good burners; featureful scanners but not necessarily the most accurate;
I got my 760a for ~ 50 after coupons and rebates; if you can find a similar deal that's another good choice. good burner; good reader; excellent (albeit slow as heck) scanner.
note that choice of media is probably more important than choice of burner. sticking w/ TY and Verbatim means you can choose just about any burner.
