i have an issue with my front derailleur; i put in a sealed bottom bracket and it pushed my chainline out just a tiny bit, but it's enough to make the inside ring just barely shiftable.
also, the limit adjuster screws got corroded into the housing, and i stripped the heads getting them free. i can turn them with great effort, but days are numbered.
so, i'm going to have to replace it anyway, should i go for a later derailleur?
any opinions?

thanks,
IMO, no, don't go for the "latest". Front derailleurs have evolved over the years so that they are very specialized- that is, they are designed to work with only a limited selection of chainrings. In addition, they somewhat depend on ramps and pins on the chainrings to facilitate the shift.

OTOH, since you have a 42-52 double (correct?) almost anything will work fine. Any '80's to '90's "road" front derailleur should be OK.
