As a recent victim of the "Passion of the Gun" in the form of 1911s, I feel your pain. I have my primary G19, a backup G19, a backup-backup G26, and love none of them. A couple months back, on a lark, I bought a Springfield Range Officer 45, followed rapidly by a DW Guardian 9mm, and a DW CCO 45. Now looking hard at the STI C Duo, and waiting impatiently for the DWX Compact to drop.
If you WANT a Beretta, get a Beretta. Everything in life does not have to be driven by cold logic. Just know going in, that if/when you realize you never carry that Beretta and decide to it, you won't recoup your investment, because the market in Beretta pistols is soft.
I'm with Rob, though. There are several DW lightweight 9mm Commander-sized guns on Gunbroker right now. They'll be inside your price range, and will be WAY more shootable than anything else you're likely to find.
