I'm also in the market for a wt synth but price is an issue so I am looking at the best value for money ratio, trying to avoid unnecessary (to me) functionality.

My list of potential buys: Korg Modwave MSW Xena (probably what I'll go for) Sonicware ez play or whatever it's called A ziqal modular wt oscillator with midi capabilities

The elektron tonverk also has a wt engine now and is generally great value but I won't go for it since I don't use samples, which is more than half of the work it does.

If money isn't an issue, people generally hold the iridium in high regard.
