The belt-driven motor on the 201-3 is not at all the same as the Featherweight. The 201-3 with belted motor will have all the power you need, as long as the belt is in good shape and adjusted properly. If there is a small difference in power, it is definitely not enough to justify more than double the price. If you're not interested in the cabinet etc, you would be wasting a lot of money on the 201-2.
If you search in this section, I know this has been discussed in the past.
