Well, start saving up. Put a few hundred bucks aside every month (or every other month) and before you know it you'll have a couple of K just enough to buy you the real deal.
I'd even recommend the Voyager but its just not the same synth. Its still awesome though.
Moog's "Little Phatty" (or little fatty) is quite nice too but I don't think you'll be happy with one since it doesn't have too many knobs. Just a few. Sounds nice though.
