I think I was pretty lucky to get mine for £50. The original winner bid £80 but pulled out because the seller didn't except paypal. I got a 2nd chance offer.
I notice from the link in your signature your 940 CCF has options for lighting. If you are using X10 it might be worth going for the UK 950 rather than the US 3000 as the RF frequency will be compatible with X10 RF whereas the 3000's RF is a different frequency. Plus a cheap Powermid Receiver will work directly with the 950's RF giving a very cheap alternative to the RF extender. (less than a tenner on Ebay for my Powermid receiver)
