For the sake of not needing as much work, I'd look for something like an 1811 or an 1864. Those are different series, but same size and hp, but the tractors don't look anything similar.
Since you're new to this, look for something like this:

Problem with this series may include a tired engine, so look for a low hour machine.

Problem with this series is the electrical system sometimes needs some work, and the rear ends tend to have developed leaks. Look for a clean machine, or one that has been stored inside.
