An NV4500 may be your most economical and easy to swap OD choice for your 1 ton, yet it is still not cheap. It is also obsolete, hasn't be made for a number of years, but aftermarket parts are still available in varying qualities.

Others will have info on that swap, and you could do a search for NV4500.

The 1/2 ton may be good with a T5 mix and match combo from a camaro and an S-10.
