I'm in the market for a home sharpener. My guy is getting ready to retire and he's been doing them for the past 30 years so with myself and 2 sons playing I figure it may be worth the investment and time to do it myself. Seems like there are alot of good options out there now for this at less than $2000. Blackstone X2, Wissota, and blademaster SPB850 all look like good machines. Also for a little more blademaster has the BRC2005B with the cross grind and I'm not sure if that is the only difference between that and the SPB850 or not. I was leaning toward the SPB 850 but I just seen some Cag One sharpeners on ebay and kijiji lately and they look fool proof and consistent every time which is enticing especially for a new guy but in looking at some reviews / videos I'm wondering if that machine rounds off the toe and heel giving the blade a banana type profile....some pics of skates you see have the toe almost completely grind down and I am wondering if anyone has any experience with that machine to say if that is the norm or if the wheel is set too high or tension on the wheel too high/low or whatever.
