It really depends on its condition. If it is almost as good as new then £180 plus 2 good thermometers and a light might just about be worth it. I have seen CPE2's sell for less but this would demand patience on your part to wait for the right item and then you have the problems of p&p.
Overall you haven't got a bargain but you haven't been done either. Can't comment on the bid tactics but if it was a set-up then this breaks down if the fake bidder wins and leaves the seller with the problem of arranging the next time genuine sale without attracting attention. A fresh sale of a similar item within days of the first sale would look suspicious, especially from a seller who appears to be new to e-bay.
