An L.C. Smith would be a good option for a sidelock gun.
For your budget, a Fox Sterlingworth or Parker VH in good condition could be had for higher end American made Box Locks.

If you want something a bit cheaper and keep some money in your pocket, the Stevens 311 is a great reliable gun. Or if you want the same with some extra options, maybe a Savage/Stevens Fox Model B.
