I was considering getting a Vita50 from BKElectronics - but then found someone on Ebay selling them brand new even cheaper ... Query is I'm a bit concerned to how they can be being sold cheaper than the direct manufacturer selling them ? Or is this Ebay member BKElectronics ... ? The location is similar .. Leigh on Sea. He has sold lots of these subs + Vita 100s ... What are your thoughts please ? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=3275&item=5771815439&rd=1&ssPageName=WDVW Thanks, Mark.
