Anyone got one? Any good?

Always see these on Ebay, and they seem very cheap. Complete waste of money or worthy investment? Someone on here must have one, quite fancy one if they are half decent...

So one to avoid then? I've not really got any idea how much a decent manifold should cost, or where to get one from. Anyone got any links to any proper ones?
