yup, up you will go
the m-audio stuff and the event pres should be roughly equivalent in quality.
and they will be an improvement over your console pres. maybe undramatic on some instruments, and possibly very dramatic on others... but a general improvement. certainly if you build up a lot of tracks.
so find your best price and go for it.
i recently was looking for some extra solid cheap channels in the $200 category and this is the fruit of my research:
event, m-audio, symetrix sx202, studio technologies mic preeminence, rane dms 22, spl mikeman, uhh. i know there are more...
some of these are going to be a little better than the others, i would say the studio tech and spl are going to be slightly classier but way harder to find (both are more expensive units- maybe $500 plus new- that have low resale value). the rane and symetrix should be solid, nice simple pres that you can upgrade later. the event and m-audio stuff are the newer, better supported, more hyped products, and are much easier to find.
totally out in left field you might be able to get a stewart or a gaines audio pre. both are very rare... but generally good. stewart being colored, gaines not.
