Roland MRS-2 Promars

via this auction

"This is pretty similar in sound to a Roland Jupiter 4 minus two oscillators and the polyphony. It has 8 user programmable patches, a great sounding filter and great envelopes."

"It has an internal modification that allows both SEMs to be controlled at the same time. Basically, the CV and Gate Inputs control both SEMs rather than just one. There's really nothing like it's multimode filter layered with another. Both SEMs have another "reversible" mod that gives them a faster LFO. The stock LFO speed was pretty low. These LFOs get fast! Think frequency modulation! Lastly, it has blue LEDs. Yippy!
All these mods are completely reversible and nothing was done to jeopardize the originality of the instrument."

Synton Fenix

via this auction

"Here's one you don't see too often. A rare Synton Fenix--- 1 of 75 made. It has just come back from being serviced and needs nothing. It's in beautiful cosmetic condition with only a few small scratches (very hard to see.) As you may know, Synton made a small number of these back in 1997 through 2000. Too bad they stopped! This thing is unique with it's 3 VCOs, 3 VCFs, 3 EGs, 3 LFOs, 4 VCAs, etc. It will come with the power supply, original manuals and some banana patch cords."

This one spotted by EB.

Multivox SQ-1 Firstman

YouTube Uploaded by synthmaven on Mar 16, 2011
Firstmans on eBay - not seeing it listed at the time of this post.
"I am posting this video of a nicely preserved Multivox SQ-1 Firstman that worked very well when I bought it years ago but now all it makes are weird pitched sounds best described by recording them and making them available in this video.

Some of the lights still come on but there is no sound.

I was going to try and have it fixed but I am running out of money so it's on eBay now.

Maybe someone else can get it fixed and restore it back to its former self.

This video is not for entertainment value but to demonstrate the condition of this piece to potential buyers.

When it works this synth have a truly bad-ass Acid sound, like a TB-303. There are videos form other users on Youtube to back this up.

Those who have already owned or heard one of these know that what I am saying is true."
