Does anyone here know anything about ATI 1911's? How would you rate their quality and reliability?

I've never had a 1911 before and have the chance to buy a new one for $500. I've always wanted one and swore that if I could ever found one for around $500, I'd buy it. I found one. Yahoo!

However, I know nothing of ATI and was wondering how well-built they are. Since my state doesn't allow its subjects to carry concealed, I'll use it for occasional plinking/target and home defense. It won't be fired a whole lot.

I don't want to spend money on something that isn't going to stand up over time.

Any help would be appreciated. Thanks.
