I think the Ion is great bang for the buck. 49 keys would probably work fine for me for playing a pure synth, but I do prefer 61 and if it were me and the sounds are comparable ( I've never played the MS2000B ) I would likely give the MS2000B the nod here.

If I remember right, the MG1 only has 32 keys ? That really was a great little synth though for what it was. It's even more amazing to me when I consider some of the other junk Radio Shack has had their name on over the years
