Decided on a Scout 300. Direct bolt in, low range goes from 2.0ish to 2.62 with a lot more options down the road. The D20 can be rear geared also but only to 3.1 or so and its a grand. Or go the 300 route, 4.1's are available, twin stick that has more options for front dig or bigger outputs. Just more room for improvement if I ever thought I would need it.
