I bought a 9mm a couple of years ago just to keep in my car, nothing too expensive. I picked up a new SAR K2P at a local store (Rural King) for $279.99, it's made in Turkey and imported by EAA out of Cocoa Beach, not far from here. It holds 17 rounds. I put a small Hogue rubber grip around the handle, it feels good. Here's one for $249 online.

If you're in Florida, Rural King is advertising the SAR B6P for $223, it's very similar but I believe it only holds 13 rounds and is slightly smaller. The website is out, but check the stores for a cheap reliable 9mm.
