The trilogies and bit 99s are gradually getting rarer on ebay. Nice sounding synths IMHO.

to get the full interest really think they should put these two mixed demos at the top of '08 demo page instead of just the leads sounds , as they bring out the analog sound by far the best IMHO.

really depends what style of work you're into I'd say. I've had both of these and the P600 is great for psychedelic, dubby stuff and the matrix for crisp techno-y/ambient lines.
