Both are very capable vehicles. However, in the long haul I think it would be less expensive to keep the Jeep on the road and trail. Parts for the most part are Inexpensive, Easy to find, the aftermarket is massive and simple to turn a wrench on. Heck, if you roll a TJ you could order everything you need to build it back from scratch via the net....as opposed to locating parts on an older Cruiser.

I have owned and wheeled both, and here's my thoughts. The FJ80 was great on the road, really comfortable ride, would seat 7, and had a good towing capacity. It also had factory lockers and was really capable offroad to be so big. The downfall is parts were expensive and it was a PITA to work on. As you probably know, a Wrangler has a relatively uncomfortable ride and room for four at most. However, parts are dirt cheap and readily available, they are very good offroad, and are absolutely tons more fun to drive than any yota.
You could probably find a 97+ TJ with a 6cyl fairly easy for that price, that's what I would look for since thats you budget. I don't have much experience with land cruisers but wranglers are very capable, and the TJ has coil springs all the way around which will give you a nicer ride for a DD.
