Diamond hole saws (45mm/60mm)

[kyl]

I thought this would be easy after some forum searching, but I'm having terrible luck sourcing diamond hole saws locally in the larger sizes 1-3/4 | 45mm & 2-3/8 | 60mm. Princess Auto, the big box stores, Home hardware, crappy tire, KMS, you name it I've hit it during this past week and nothing. I've also tried some tile and glass shops, but they either don't deal with selling hole saws or only source industrial ones that aren't for DIY.

Does anyone have any hidden gem suggestions, or should I just bite the bullet and wait a couple weeks for some cheap ones from ebay? Princess auto was apparently the go-to previously, but they only had two active SKU's in system and they were for multi-bit kits.
