glock all the way over a SR9. i have several glocks. thousands of rounds. not one issue. not a one. love 'em. if you can handle the lack of asthetics, they will never let you down.
i've heard a few stories of the slides on SR9's detaching from the frame after about 400 rounds. this happened to my buddies dad so i know for a fact that it's not just internet rumor.
my personal experience with ruger has been revolvers = awesome. autos = suck. i have not yet found an exception to this simple equation. i would never part with my ruger 38's and 357's. i've dumped plenty of P95/P98 and my LCP. my personal opinion for what it's worth.
if you're looking for a cheap 9mm auto, buds gun shop has S&W sigmas for $329 delivered plus the $50 rebate from S&W or 2 free mags. i'm seriously considering one of these myself.
OR Summit gun broker has police trade glocks for i want to say $375 (some with night sights even

), they may have some beretta 92's left. last i looked those were going for like $275.
I recomend Thunderjohn here onthe board to do a transfer if you pick either of these up. He's a great guy and super easy to work with.
