Well as with everything on ebay it comes with a risk involved, especially if your not dealing with authorized dealers (offically acknowledge and listed as such by the manufacturer.)
While many times the price is alot more attractive, the risk involved for getting damaged goods or even not the same item(s) that you would if you bought it from a trusted dealer online or locally is real.
For instances, every rotaluxbox sold today from offical authorized dealers (at least in EU) comes with a rotalux carrying bag, not just the cardboard box. Most people selling "new" rotalux boxes on ebay does not include that bag...
As for [Godfather] and Supremekey, i cant really comment. I do however have a transaction pending with [Godfather] and time will tell if it was worth the risk or not.
