My synth setup is pretty modest, but I love 'em all the same. I use a Roland Juno 6 (pre-midi) and a Yamaha CS5 mono synth. I also have a Fender Rhodes, which I realise isn't a synth but it warms up any track.
There's a known problem with my soundcard, which makes it freeze up the moment you attach a midi cable! (No fix is likely either - so ain't it great when you buy something that only half-works

) This means I don't have access to softsynths, but hey, technical limitations are creative possiblities....
If someone placed a couple of grand in my hand and said "hey boy, go buy some synths!", I'd source an ARP Odyssey Mark I and an OSC Oscar. Stick them through a distorted flanger and get that Connie Plank/Billy Currie 'weeeeogghhhhhh!' sound.
Two thousand pounds to go 'weeeeogghhhhhh', there's dedication/addiction/madness....
I also really loved the Memory Moog that Ian Nelson used to play in Fiat Lux. Really unstable beasts, tuning-wise (I'm told), but they made some great sounds.
Another really good set of sounds I rediscovered the other day, were on a Revox Cadets track on the Cocteau 'Signature Tunes' LP. (I think RC was a pseudonym for BN, himself). I've no idea what synths Bill used on this track but it sounds superb, classic 80s Bill Nelson.
Anyway, enough from me.
Have fun bending electricity....
