The T-56 while cool and fun is not cost effective. An 80e is the most cost effective most reliable route for your average joe. A built 60 in a RCSB will have a little easier time than say in a Crewcab. If you plan to stay under 500ish a built 60 is fine, but in the long run a 80e is just a really good option. The 80e with a good stall and the right gears is a great combo. Simple and straight forward.
