IMHO the Hip Hop board has better drum sounds than the Techno board.

If you get an XV unit, check out the new 64MB SRX drums board. There aren't that many patches on this board but the drum samples are the most fantastic I've ever heard from anything this side of a sampler or a Roland V Drums system! Honestly. Unfortunately, I think that $799 Australia is way too much to pay for these boards! However, if you crave drum sounds, put this board on your shopping list if getting an XV synthe! It's great.
