More resources? I dont know what you mean. Just go for SX2; SX1 has some serious problems. Why would you wanna "buy" an older version anywayz haha. I say go for SX2.
Cubase VST 5.0 still doesnt have all the bugs out. By the time all the bugs are out of SX2 they'll be a SX8. But atleast the bugs in SX2 arent as bad as the ones in SX1. That shit disapears out of nowhere without saving and corrupts songs left and right. I wouldnt touch that shit anymore. SX2 seems better so far.
