I recently got a Paraordnance stainless GI Expert 1911. So far it looks to be well built especially for the price. I paid $675 including tax. I've seen them for a little less but this local guy actually had one and was really nice/helpful to do business with. Hopefully I'll get a chance to shoot it this afternoon after having it for over a week and either having to do other stuff or dealing with shitty weather. As soon as I get through doing some changes to the finish I'll post pics of it.
If you just want something to shoot, get a Springfield GI and send it in and have it tuned up. It'll probably shoot better than most are able and cost a lot less than a custom. Most of the "expense" on customs are just bells and whistles that add very little to their accuracy.
