Best advice is take someone with you who knows Cherokees and specially those that have been lifted. There are a lot of hacked up Jeeps out there. You are better off getting one that is still stock and doing the work or having someone you trust do it. $6k should get you something decent. 2000/01 XJ's have a head cracking problem and the 98/99's are considered the best years by many. Good luck.
