Glad so many people are saying Yamaha CS-5... wicked wicked little synth. multimode filter plus sample and hold that you can put things through. 1 Osc but it's a pretty good one. Recommend using it with a good pre though, it can be quite quiet...
Got mine for ?80 ($130?) and I'd never sell it... Bass in this track is a CS5 and as you can hear it's quite bassy

Juno 6 is absolute meat and potatoes standard too... Basically a scaled-down Jupiter. SUCH a good synth for $. Steady tuning means you can tune it quick and it sounds good immediately unlike more complex vco-based synths that require constant balancing of tuning to get the same sort of sounds. Folk think they're not as good as 106 because of midi non-sense but 106 are built very poorly in comparison and parts fail left right and centre...
Also DCO stands for digitally
controlled oscillator and is digitally tuned analogue, not a digital osc... No digi osc could sound like that!!
Korg MS10's are seriously juicy too... Maybe a bit more pricey but listen to The Emperor Machine's "MS10 Demonstration" which is entirely made with an MS10, you'll know what I mean... His track "Sh-09" is a great another demo that the Roland Sh-09 is capable of making very good records on it's own (despite what the geeks may say).
Get any of them and maybe a moogerfooger filter or ring mod (?150) or something to give it a little bit more grunt and scope for tone and you'll have an infinite spectrum of juicy sounds to choose from, forever more...
would anyone agree with me to say Seils are a pretty interesting option? maybe an acquired taste... not for bass.
