well if i was you i would go for the one you have test driven and seen for yourself
get a compression check done... block check (check for exhaust gasses in the water) if your compression check is 142 or above even throughout the cylinders you should have a good engine
but let you mechanic decide that for you
if it hasn't blown it's head gasket yet it most likely will... so prepare yourself for that... doesn't matter if it's 86-92 they all suffer from low torque on the head bolts which in the end blow their head gasket...
you'll know if you get this problem as you will start having strange temperature problems, spiking etc etc... just keep an eye on the temp gauge and make sure you don't cook it
as soon as you see temps starting to climb above normla pull over and stop the car, get it towed home and get the block check done... if you were clever enough to do this you won't have damaged anything and you should be able to just get your head checked to make sure it's not warped or leaking etc, buy a new gasket, new toyota head bolts or (recommended) arp head studs torqued to 72ft lbs and you should still have a beautiful car
or you could get really adventurous and when you blow your head gasket do the turbo swap :P
good luck with it and don't let the head gasket thing worry ya... there's plenty of help around and if you treat her good she'll be good back
