You can create up to 100 user styles on the Boss DR-3. The only downside I'd have to say from the start is that there is no media card storage. However you also have to take into account what you get for the price.. The sounds are really good in my opinion. I think several of the kits sound like the (V) Drums that Roland is so popular for. Here's a basic list.

Styles: 100 preset (with bass)
100 User (with user bass)

Songs: Up to 100 user songs

Max Poly: 12 voices (which is good
considering it's just a drum and
bass machine)

Kits: 50 preset kits and 50 user kits

Pads: Velocity sensitive, and several kits
include mutlilayered samples on a
single pad (meaning you can do "ghost
notes".

Recording: Real and Step

Connectors: L/R output, midi in, (2)
footswitch, ect.

These are just a few of the basic specs. There's also some effects as well. There are several effects to change the sounds of the kits (themselves), and there's also separate (ambience) effects to adjust the (global) sound. Again the only downside is lack of smart media card, but for the price you get a lot.
