Can't go wrong with any of the big names if you find one your comfortable with.
I like the SIG 229 and 239 the best as far as SIGs go. I'm growing more partial to .40S&W and .45, but my "never leave home without it" carry is my lil Kel-tec .32, that I'm hoping is going to have a .380 cousin delivered shortly. Either in Kel-tec or Ruger variety.
Buds has SIG 229, 226, and a few other CPOs for around $550 I believe.
