It doesn't look like much in the picture, but this is the Aurora AR1, a new all-analog 3 oscillator monophonic synth being built in Bedford by Adrian from Synth Restore for just £500. It's fantastically old-school, with no MIDI, a 12db filter that should sound more Oberheimy/ARPy than Moogish, and a real hardwood case. Send him £150 deposit, and he'll build you one in two weeks.
I've been looking around for alternative analog synths with keyboards: You could get an old Jen SX1000 for around £150, but it only has one oscillator. A Sequential Circuits Pro-One is very cool, and has an arpeggiator and sequencer built in, but the sounds are more basic, they're fairly unreliable, and a clean, restored one can cost £600+. A Roland SH-101 has a definite retro charm and costs about £250, but again, has only one oscillator. The Soviet PolyVox is also very cool, and has two oscillators, but is still much more basic than the Aurora, for around £250 (plus a lot of postage). You might find a Moog Prodigy for £450, which is obviously an impressive thing to have in the house, but to get close to the Aurora's power, you'll need £1,000+ for a MiniMoog
