For me it'd all depend on how much... I think they're about £600 without the touch controllers? So if someone said to me £350 second hand with the touch controllers, I'd be all over it like a bad rash. I could probably be arm wrangled for an extra £50...

There isn't a huge amount for them right now, but I reckon it's going to explode in the next couple of years. You'll need a pretty good PC though to do it justice!

£450 with touch. And a bit far to drive to collect.

I've a fairly beefy pc, nvidia 980 graphics. Not cutting edge but powerful enough for it.

I have (in theory) bought a complete (very local) second-hand HTC Vive rig for £560 on Ebay, but the party of the second part hasn't responded to my email pleas to pick it up for 30 hours, so I'm starting to get fretty.
