Having both a 98XJ and an 89YJ it would be tough decision, the YJ's up to around 91-92 up in this area can be gotten under $5K if you shop around. Some of them are in very nice conditon. Look for one with the 'dual top' option, the hard top in the dual top comes with full doors with wind up windows, soft tops come with half doors and soft windows. Soft tops have no security unless you put in a tuffy lockbox or center console.
All that said, I grab the YJ on nice days, top and doors off and spend the drive with a big S*it eating grin on my face. It is also warm in the winter with the hard top on though a bit noisy, consider the aerodynamics of a XJ= contoured brick, aerodynamics of a shorty=big barn.
My only real thought of a downside to the shortys is working on the tranny or transfer case, they have one whopper of a plate under there and while I have not had to get intimate with that area of the undersides of the YJ 'yet' it looks like it could be a royal PIA.
My next is a TJ dual top either sahara or rubi, depends on how good the business does this year.:anon:
