Which 300B to choose ?

Question for the 300B Gurus out there as I have not been in the 300B game since the Cetron was the only game in town.

Got a pair of Canary Reference 2 yesterday - They need 16ea 300B output tubes for the pair so obviously cost is a consideration, have looked at the PSvane ($155 Pair) and the Shuguang ($110 Pair) are there any other 300B's out there that is worth taking a look at that can be bought for a reasonable price?

Thanks in advance,

Peter
