It seems the quality of sharpening I get at my LHS is pretty hit or miss as they have a wide range of employees in terms of age/experience. This device is extremely tempting to me with having a 4 year old who's skating 2-3 times a week and then I also skate 2-3 times a week. Break even on the cost will be a while but there is definitely something to be said for convenience and consistency. What to do, what to do :-)
