Get a rig that has sound mechanicals period. Wether it has ifs or efi whatever you can find and can afford go for it. If you can find a good deal on an ifs rig with efi get it and do a sas. It isnt hard to do by any means and it is actually cheaper to build including the price of doing an sas. Dont be affraid of efi either. My 90 is the first 4x4 Ive owned that has it and I have had absolutely 0 issues with it. I was actually planning on putting a carbed engine into this truck if the efi engine didnt run but of course it did, so away it went.
