I am not sure i would shell out the £500 - £600+ they go for at the moment...
There are many other equally enticing cheaper monosynth options around at the moment, most have easier midi connectivity as well.
But if you think you need that sound again (you had a 202 before) then go for it! it opens up quicker than the 202, but the 202's sequencer eats the 101's!!
Of course the 202's sequencer ain't for lightweight programmers
