Ventus Ltd without the flashy paint retails for £700, so you should be able to get that if you can find a buyer who particularly wants that special edition. I doubt that they're really collectible as they are recent production and have already been marketed as a special edition, so it's likely that everybody who desperately wants them will have got one when they were first released.
Are they the +6° or -17° version? If they are -17°, I'll give you £500 next spring, so there's your baseline.
