Take a look at Williams Gun Sight Company they list several side-locks at very reasonable prices. I have purchased three side-locks from them for under $200.00 each and they were all in great shape. Right now they have a CVA Hawkens listed for one-fifty which should be a good buy. Their sales people are honest and will tell you if there are any problem with a gun they are listing. Several of my friends have purchased guns from them and none have been disappointed.

P.S. Look at the Mendi they list, I got one a while back and it is a real good shooter.
