The MOTM-440 is a discreet version of the famed SSM2040 filter chip. I am very enamored with the way that this guy sounds. Its just so smooth and well.... nice.
MOTM is making PCB's avalabe to the DIY comunity again.
Check out the sound demos here: http://www.synthtech.com/motm440.html
I found a set of PCB's for a Milton Sequencer on eBay for only $40 bucks.
The Milton is a killer design, although it's a controversial project. The original designer is none other than Peter from Plan B. If you don't know why that is a big deal for some people well lucky you. If you relay have the time then check out 36 pages of weirdness at muffwiggler.com
Not to sure when I am going to get around to building this guy, but I think it would go nicely with a Lunetta.
