I am No expert but all depends on your budget. If you want to go for lc 40 then have a look at forsale section there are many nicely done fj40's for sale and save your self from all the trouble,(price range is from 4.5 lacks to 10 lacks)
and i think 70 series can be kind of an all rounder army auction RKR can be found till 5.5 lacks and restored or already restored one are there too around 10 to 15 lacks.
