That's the right eBay location. They have the full range of SS Master bats.
This one cost me £200 posted. I know Onlinestockist had some on their Facebook page a while ago that were a bit less (without the postage) but they didn't know when they would be getting anymore or if they would have lighter ones in.
Kaboom Cricket provided excellent service and the bat is fantastic so I don't mind if I paid a little over the odds to get one exactly as I wanted (8-10 grains, 2lb 9oz, no blemishes, minimal concaving etc).
