It's a good kit for Session Drummer. You will miss the power of Superior Drummer though. If you haven't bought the Joe Barrese Evil Drums SDX for Superior, that might be a more useful kit because of the sampler.
That said, $19.95 for a sample set is a big bargain so do without MacDonald's for lunch a couple of days and buy the kit. Rail at Platinum Samples will surely appreciate another sale. Can't say more than this, but keep your eyes open on the Platinum Samples site, Session Drummer 3 users.
