I'm typing on a 2030 (1st generation, Dvorak) for 7 years now and I really like their layout. Especially the vertical shift keys in the home row work very well. There's also the very useful Fn-Cut-Copy-Paste row on the 2030 that the 2020 doesn't have.
If you can afford it, I would go for a 2030 instead of a 2020, even better imo would be the 1st generation 2030 as its modifier keys are better positioned. In any way, be prepared to spend some time learning the unusual locations of enter and backspace. Personally I'd say it's totally worth the time. BTW, I have no trouble switching between the typematrix layout and an ordinary, staggered keyboard.
