If you want a new one and save up for an Ed Brown. If I'm paying that much for Ed Brown parts, I want them to assemble it. The old guns were pretty good, but they were notorious for proprietary stuff. They seem to have their act together under the CZ umbrella.
Actually, there's a small amount of difference between the two nowdays IMO. Dave Severns over on 1911forum has broken down the differences and the fitting is very comparable. Not taking away from EB by any means, but there's a bit of name premium in those guns, kinda like Wilson in comparison to new DW models.
