Chrisso good idea with Spectrasonics (and Ilio their parent company). Most of their stuff is top notch. If they have something on offer it might be very good.
However I think the Burning Groove CD is a bit dated and it doesn't sound really good to me anyway. Too much over-the-top cheapo spanking to start with. Peter Erskine is the opposite, a bit too drab. It's very clean and natural sounding but it doesn't have any balls. You have to seriously abuse the sounds to get some attitude out of there. I once heard a CD by Steve Gadd that sounded good but I don't know what's up with that. It's probably an old release.
The best thing would be to hunt around a bit. If you have a fast internet connection. Go the the "Soundsonline", "East-West" and "Ilio" sites and check their stuff. You can download demos and see what sounds might fit in your type of production.
There are two ways to go at it really. You either find sounds that sound very produced and polished and don't touch them, or you find basic ones that you have to manipulate with the rest of the kit to shape into something that blends well together.
Good luck and keep us posted on your findings!
