FWIW mainstream dealers are doing these bundles for close to this questionable eBay deal price, with better customer service. Audio T have been doing the BU250 plus MA BR1 speakers for 799 and Sevenoaks have been matching them (in the store I visited - Southampton). Sevenoaks and other hifi shops seem to class Sonos as 'computing' and do not seem to sales discount the individual components, but I got the strong impression that you would be able to get 10% off the BU250 bundle if you didn't want the extra speakers and had a genuine price from another dealer. This actually showed on Audio T's website for a couple of days, but was changed, possibly due to manufacturer input or possibly due to sales targets. Anyway, for those that missed out, I would ring your local Audio T / Sevenoaks and see if they will do a BU250 for 720. Since you'll get a chance to look at some other kit and put some business their way, though I doubt they make much money out of it, it might be more fun experience. I myself spent 3 weeks pouring over eBay for a ZP90 around 200 notes and it got on my nerves to be outbid all the time.

All this started as I didn't realise the ZP120 could not double up as a stand-alone player...
