Check the Demo's of ALL!!!!!!
if you dont want midi, and you probably will eventually, check out N-Tracks, check into cakewalk, if that's your cup o tea, buy the cheapest upgradable version and upgrade to sonar at there website, but a software purchase is a major decision, once you pick a major brand you're pretty much stuck with it cause of familiarness and upgradeabillity, unless you have the money and time to start from scratch. I'm stuck with Cake, but that's a good choice all in all, but try Cubase, sonic foundry, etc. etc, you should stick to the major brands though, even though any one of them could sell out to another company at any given time.
This is one of those "UP TO YOU" but guided decisions, just like sound cards
