Online Drum machines

Being a poor student I really don't have the funds to go out and purchase a drum machine, at least not yet!

Therefore I have thought about using an online (or free) drum machine, but are they any good? If anyone got any urls or anything, and/or suggestions I would love to hear/see them

Thanks and cheers

iam not really sure i heard leafdrums 2.2 is good( i think its shareware, good luck on finding it). I use to use midi drums from mysongbook.com with guitar pro.

Have you tried free drum loops instead. They're a lot more realistic sounding.
Just look up free drum loops in Google by BPM
