I'd throw the Smith and Wesson M&P 2.0 into the mix too. It's an upgrade over the budget model SD9VE that's more similar to Glock 19 quality.
There's dozens more high quality options, I'd really suggest the the Glock or M&P if you can muster the $500-600. Go for the he SD9VE if you can't. It's probably worth looking for a night sight version of whatever you choose. This place is advertising
M&P Compact 2.0's for $350 with free shipping. You should be able to find a local FFL that does transfers for under $30 pretty easily.
(I don't know anything about the above linked seller)
Consider buying used too. There's a couple pretty decent deals on pre-loved Glock 19s in the Classifieds.
