Go soft... they're much more powerful and able to load many more samples many times faster than their counterparts. And unlike hardware, they're easily updated so you dont have a piece of hardware collecting dust in 5 years. I use halion alot and for the price it is simply amazing. You also might want to check out Kontact which has just started shipping. It's supposed to blow the competition away. Halion load Akai, emu and many other formats also and you get the added bonus of keeping all your work in the same daw environment.
