Reason has some fantastic features: ReDrum is still my drum machine of choice, Maelstrom one of my most-used synths, and the novel 'patchbay' setup leads to some crazy signal paths that you couldn't come up with in other DAWs.
However, it is weak if you want to use audio, and the lack of VST instrument support is a massive, stonking curler of a deal breaker for me. The tools provided aren't 'clinical' enough. No frequency analyzer, no graphic EQ, no high pass filter, you get the jist. I say spend your hard earned moneys on a more conventional, comprehensive workstation, and get Reason at a later date, and, rather than using it standalone, ReWire it into another program and use it like a set of plugins.
