Don't rush - get the gun you really want. SR9s are generally much cheaper than Glocks on the used market and they show up here from time to time. I've seen P95s for $250 more than once - they were never pricey to begin with...
Thank you for the advice, I'll keep shopping around with the websites and information everyone has given me until I can make a decision. I always find it interesting how on the internet you always think you're getting a good deal, but after the ammunition, fees, etc. you're really not coming out ahead if you'd of just walked into a shop or done business on the ODT.
