If you like the 637, but are afraid of hammer snags AND aren't married to the silver finish, there are still some 37-2 models available on the market with factory bobbed hammers and no ILS. I paid less than $400 for mine in 2005 IIRC, but I've seen them in the mid $400s as recently as this summer. Otherwise, I'd get something from the x42 series (042, 442, 642, etc).
