One is EZ the other is Dolphin...same product different name? The other issue is that the set is in eastern states I'm in western Canada and with shipping and duty, I'd likely wind up paying closer to $200.00 for the same Item you only pay 110.00. Even though the $ is close customs and shipping really ad up. I ordered some parts the other day from Big Jim's....$40.00. Customs nailed me $37.00 just to open the box and confirm that they were parts........I'm really PO'd over that one.
