Thought I'd update my situation here: I spoke to a few folks at MSH, namely Chadd and Gummer - thanks again for your kind help, really appreciate it. Also got in touch with Mark from Blackstone Sports, who has been extremely helpful and informative. Should probably mention I do currently reside in Taiwan, making this whole situation a little more complicated than it should be. While I haven't finalized my order yet, I'll be ordering 2 spinners (90/75 and 100/50), 2 orange wheels, 6 rubies, an accessory kit, one extra fine shine, timing belt, spinner cap, felt pad and whatever honing stone Mark ends up recommending. As of now, a buddy of mine will look to chip in as well - he will be doing most of the sharpening, but I'll cover the majority of the funding. We look to sharpen about 5-10 skates a week, and will likely be the sole FBV provider in northern Taiwan. The only other provider is in southern Taiwan, and he apparently charges NTD 500 per sharpening (roughly USD 16.50). We're not looking to run a business - this is purely to cover the cost of the machine itself and money on the side for the amount exceeding the original cost. Aside from the learning curve, a concern that was brought up to me was the amount of harmful dust particles it creates. Since we mostly live in apartments in Taiwan, space comes at a premium here and is not plentiful; thus I believe some form of custom DIY ventilation vacuum system is a necessity. I've seen some photos on this thread - was wondering if anyone has an extensive guide in terms of ventilation? Worse comes to worst, we pull that sucker down to the apartment underground parkade and do it there; or set up a hotdog stand somewhere (without the hotdogs).
