Really, I was thinking about that, but I thought they were more expensive then 800?
There are several quality 1911s that can be had new for around $700-$800, including any number of Springfield "Loaded" models and the SW1911, all of which are excellent.
The Taurus PT1911 can be had for around $550-$600 and serves as a functional "entry-level" 1911, but for not much more you could step up to something truly nice.
Dan Wesson and SIG 1911s are stellar products, but hover closer to the $900 mark (and up, depending on model). I myself own a DW CBOB .45 that is built to an amazing standard.
Rock Island Armory makes a competent basic 1911 for around $400 if you just want to try the platform or want a mil-spec configuration on the cheap, but these tend not to feed anything but 230gr ball reliably and are, as you'd expect, built to a lower standard.
Finally, I'd stay away from Kimber, their QC is such a crapshoot right now I wouldn't even risk it.
That said, if I had $800 burning a hole in my pocket, I'd pick up a CPO SIG P220, P226, or P239 to complement my P229 or a Beretta 92 variant and spend the rest on ammo/holsters/magazines. But that's just me.
Explore the market a little bit and see what YOU like, then buy that. Don't worry if half the board tells you to get a 1911.
