RIA are the best budget 1911's and great beater guns. Everyone knows Para's suck and Crapbers also are just overpriced. Of course Colt is the ultimate 1911 but Remington does make a damn good 1911. Ruger is my favorite and I believe is priced the best. You can't go wrong with it for $700.
Colt is far from "ultimate" these days, but they've usually had a rep for making a halfway decent gun over the years. I've had two of them and they were great, wouldn't turn down a good series 70 or 80 gun at a decent price if it was available. The ones I had were officer's mods, if they were 5" guns or commanders I probably would still have them. (Not that an ofc mod is bad, I just had no use for them anymore as carry guns. )
