OK im looking to record my band at the rehearsal studio we play at.

cheapest would be to rent gear!

there are tons of products that would be great, my band just bought a Presonus firestudio, which has enough inputs to record a full band live,

we've been messing around doing pre production and demoing songs for our next full length. When the time comes, we'll be renting more gear to do the album.

check out my bands site (in my sig) we have vids of us recording and stuff, you can lsiten to demo tracks on myspace.

good luck with everything,
