Gotta agree with the other guys. Hardtops go for around $2,000 on up. Unless it's your preference to have a hard top, you can get a soft top for almost 1/3 of the price (and you can use the money you save to add $1,300 worth of parts elsewhere on your TJ).
This is what Jerry is referring to: Sailcloth Replace-a-top
. The specific model number you're looking for is 79121, second from the top on the list on the right-hand side of the page. It includes the top and the half-doors you need.
Quadratec has a sale going on
that essentially knocks out the price you'll pay to have it shipped. I would think other retailers would price-match them if you'd rather order through someone else, though. The link I posted is for the tinted windows. The top is also available with regular windows, too.
