Cheap Carbon Clincher Wheelset for SS

I'm looking for some cheap as possible carbon clinchers. Ideally around 40mm rim, all black (no logos etc) and in fair condition. Maybe some Chinese carbon clinchers that someone is looking to get rid of?
Thanks

anyone? It seems like these never show up on ebay etc. Are they that good that nobody wants to let them go, or that bad that nobody buys them?

Are you after the rims only?

No, I'm looking for a complete wheelset with flip-flop hub. Ideally, matte UD finish. Sorry, I should have been clearer in my first post.

Ok, have sent you a pm

How cheap is cheap?

It looks like cheap carbon ones can be had for about £280 new, so under £200 ideally but it depends what they are. Might well be looking for the impossible.

£280 from China is about right.
The issue is import taxes and VAT so that £280 quickly turns into £350.

I have two sets going spare, both 50mm UD carbon.

One with "standard" matt UD rims with braking surface.
Novatec flip flop hub rear, disc front which I have been using as a normal hub.
Has flat aero spokes.
Owned from new by myself, low miles:

£220

One with "wide torroidal" lacquered UD rims no braking surface.
Prototype Goldtec 28h hubs which are brand new.
Spokes are brand new double butted ACI stainless steel.
Rims have been bought used from Rapha Famous @ekudduke.
Built by myself and unridden:

Cheers, the ones I was looking at said they were shipped from nottingham...although the person replying to my message definitely didn't know English as their first language.

Maybe it's all getting too expensive. I was originally looking for a pub bike...saw a nice frame and now it's turning into wanting a nice bike but as cheap as possible.
