I have about £250-300 to spend, and the rolands will probably be bought on ebay.
I play mostly RATM, Muse, and other rock/metal/shred artists (but not limited to metal). I'm also looking for some weird sounds, hence the synths.
NOTE: they will all be used for both live and recording (at home). My big concern is if the rolands are usefull for live gigs.

Thanks UG!

EDIT: all other suggestions ar welcome as always.

Thank's, im checking it out on a guitar world review on youtube now. Though keep in mind that im not explicitly looking for just tom morrello's sounds.
