While I have to correct Rozo on minor technicalities, mainly being that Mixcraft has a full version at ~$80 (with it's own good share of instruments and effects), and a "Pro Studio" version at ~$150 (which includes another Acoustica product and even more effects and instruments and can basically be considered an "add-on pack" to Mixcraft), I will agree that Mixcraft is mostly entry-level so far, mostly because there are some things in it that aren't quite as sophisticated as other DAWs have (sidechaining, advanced automation editor). However, Mixcraft have some decent instrument samples to use, as well as a pretty large royalty-free sample library to pull from (~6000 samples), and they also have a piano roll (then again, most DAWs do. Some don't, but most do).
I suggest you look around and try out some demo modes, see what you like, and what kind of functionality you'll get for the price of the DAW. Keep in mind that some DAWs have ridiculous demo restrictions (FL won't let you reopen files you saved earlier while in demo mode) while others aren't as strict (Mixcraft has a 14-day full-functioning trial, after this period you can't mix down to audio files but there is a workaround for this built into the DAW). Just go find what works best for you
