They do make sweet rigs! If you can stick a doubler in them and fit 33" tires with a Solid axle you're golden. You just got to find some sucker that doesn't appreciate what he has.
On a serious note I would reflect back on why you sold your Tacoma. I remember you having problems with the expensive steering rack and thinking it was too nice for what you wanted to use it for.
I am with Kurt on the 100 series being more relliable and overbuilt from the factory (less weak Links). A lot of car companies including Toyota do not overbuild their 4x4's like they used too. The Landcruiser is a premium product and that is why you pay more for them.
The 100 series is very popular among overlanding enthusiast for a reason, they are reliable and less likely to leave you stranded. If they weren't a step above the Sequoia or 4runner in quallity I think less people would be building them for the sport.
I also beleive that you get what you pay for. For example a loaded Landcuiser lists at $76,175. A loaded Sequoia lists at $63,080 and the 4runner lists at $42,820 (All vehicle were priced for the current model year). The lists of creature comforts are about the same with all models. The Sequoia has the same 5.7L engine as the Landcuiser so you can't tell me you are paying for more power. In the end I am sure you are paying for a better built vehicle below the leather interior.
