Mini-14's are getting harder to find at a "reasonable" price as far as I'm concerned. I still have one from 1976 that I don't guess I'll ever part with.
I looked on gunbroker and there is one that is being bid on that might go at a decent price. There are several days left in the auction so it may go through the roof, but right now it is only at around $360. You may want to look at it.
Good luck in your hunt.
