I was in a situation similar to yours. I purchased a 97 TJ last fall with a hardtop installed, and a Supertop stowed in the rear. I downloaded some installation instructions for the Supertop, and it looked so complicated (plus parts were missing that I would have had to order) that I did not even try. Instead found a good used original TJ soft top with frame on Craigslist for $400, installed it a few weeks ago, and have been very satisfied. The fabric on the factory top appears heavier than the Supertop's.
If procuring a used original top, there are some hardware bits you need to ensure are included, or else you will spend time and money tracking them down. I would recommend purchasing it in person, don't try to have one shipped:
--header rail--be sure it includes the buckles (clips? what are these called?)
--door surrounds--these can cost $100 or more used;
--roll bar brackets--about $15 each from your dealer;
--knuckle ends to attach the roll bar brackets to the top frame--these fit into the ends of the bows, set of four aluminum ends easily available via aftermarket for about $30;
--rear window bar--occasionally available used, or from dealer for too much $$$;
--body clips for rear window bar--available at your dealer for about $35/pair, but be sure the part number is compatible with the rear window bar because they did change over the years.
I haven't taken the time here to dig up details like the official technical names or part numbers for these but can do so if there is interest.
