I've got a Smith Evolver and while it has some great qualities I hate the interface. Not very intuitive or user friendly. Great price though. Hybrid

Mopho looks great too and it is even cheaper and I believe totally analog signal path though it has digital control of the analog elements.

Atomosynth - Nice prices, haven't tried. Analog

Meeblip -Digital. Looks cool, very cheap, kit.....but looks like it would be an easy kit of build.

Sound Lab Synth
This guy builds the Music From Outer Space Sound Lab - Analog, No midi, I especially like the semi-modular version that he does.

You can find other people building the MOSSL and sometimes selling on e-bay.
Shruthi 1 -Hybrid - Cheap, very cool kit. Needs you to be able to solder to build it.

Waldorf Blofeld -Digital. Looks cool - a bit too expensive new ($699) but I've seen them go used for about $400. Lots of options.

Gotharman DeMoon - Digital - Just under $600. Don't know if you could find one used.

I haven't included the Korg Monotron because it seems like more of a toy than an instrument to me. Maybe you like it.
What else have you found that is cool and cheap - Like maybe less than $500? What have you owned?
