The only 1911 22LR you will find for<$250 will be a used one, if you can even find one. The Chiappa is an OK gun; they can be real picky about ammo. You can find Citadel & Cimarron 1911 22LRs, but they are made by Chiappa. Next up in 1911's would be GSG, Sig Sauer or Umarex/Colt and they all go for $350 to $400+ depending on the model.
You can find 22LR pistols in your price range, but they most likely will not be 1911s.
