Sorry to say it,but I think you missed the boat on the sympleSeq -
He has a few boards left, but the parts kits are gone,and I don't think he's planning to
do any more runs of this project. I just checked the website, and it looks like hes got a total
of 10 more now.
That being said, it's a really nice project. If you decide to do it, check with Ben Marshall at
reSynthesis for front panels. I bought his quad, and it's beautiful!
