Start with a psr 3000.

then you'll have an idea of what you want.(damn sure that you'll keep 3k even if you get a G70 or pa 800) after.Because it is lighter than G(lightest arranger with USB to device,VH and video out),better OS and styles than PA,it can be a great 2 nd KB.T2 can be a little too much to invest if you don't like it.3k is a good addition to G,Pa and SDs.

So even if you got G or Pa after that you'll be playing more 3k for sure.
