Hardtops are easy to find, it's the full steel doors that are expensive. Now is buyers market as most people don't look for a top and doors until winter. I would worry about finding a jeep first, then if it doesn't have a top you can look for one. You'd be surprised how many you'll look at that will already have a hardtop. I paid $800 for my top and doors for my "85 (good deal). You should be able to find a set for about $1000; expect to pay $600 for later style doors and $350-$450 for a top in good shape. If you find one cheap with a rusted out rear gate you can get a fiberglass rear gate for $150. Good luck.
