Personally I wouldn't take a chance on a Taurus, especially if I was ordering online and not from a brick and mortar store that I could check it out in person before buying.
If you are buying online, I would recommend using gundeals to check for the lowest possible price. Just find the UPC number for the gun you have selected, and enter it into the search box, and it will give you the prices for that gun from a number of sellers. Here's the listing for the Taurus G2C (Bi-color... the all black is a bit cheaper)

Are you dead set on a double-stack? You can find a Smith & Wesson Shield or a Walther PPS for not much more, usually in the $250-270 range. They have lower capacity, but much better reputations for quality control. Or if you aren't willing to go that high, I'd suggest shopping for something used. You might find a good used Smith, Ruger, Walther, etc. in the $200 range.
Police trade ins are usually available in the $350 range, which is higher than you mentioned, but a good price for a Glock or SIG. They're usually full size service pistols instead of compacts though. (Oh, and avoid 40 S&W. Too many 40s are build on frames sized for 9 mm, and the 40 kind of beats up the gun after a while.)
