That's a difficult question given the fact that you do not state the type(s) of music you listen nor how many albums you have. Please be specific next time.
A good starting point in moving magnets would be the Van Alstine modified Longhorn Grado (www.avahifi.com) or the Shure V15 Type V.
For high output MC starters I would definitely pick the Sumiko Blue Point (not a good tracker, but great spatial imaging and musicality) or the Ortofon X3 or X5 (good tracking, good dynamics, accurate). Dynavector would be a good choice in the same price range, too. You can find a brand new X5 here in the classifieds for $110. That's grey market (Hong Kong), but it would definitely be the best performance dollar for dollar (lists for $325) you could get right now.
I'm not going to get in the low output MC arena. Too complicated and, IMHO, not really worth the extra trouble and money.
