I rate the Industrial Strength ones from loopmasters pretty highly.......some good single hits and stuff aswell as loops if you just want to get something down quickly.
Drum & Bass Tip Trixxx Vol 2 has some tasty bits aswell, the hi freq hits are real nice for filling the sound of a break.
There's a really good snare hit in the free demo of Jungle Drum Kits vol. 2 futureloops.com/product-jungledrumkitsvol2.php called FL_JungleDK2_Namdapha_Snare3 (it's the last snare in the demo).

That's obviously a tight, jungle snare sound but I also like the first snare in DnB Rough Connections Vol. 4 bhksamples.com/shop/rough-connections-vol-4/ called RC4_Snare (1) (it's the very first snare in the pack). It's a really nice dance floor smash type snare. Sounds really crisp and punchy.
EDIT: I'm about to get KJ Sawka sample pack hoping to get some really live sounding hits and clean, classic loops. loopmasters.com/product/details/208
