That's the decision I'll be trying to make by the end of this month. From Blackstone what I would get (X-01, 2 extra spinners, hone, edge checker, oil) would be about $970. From Sparx what I'd get (Sharpener, 2 extra wheels, and eventually edge checker when they release one) will likely be just over $1100.
Been trying to weigh pluses and minuses between the two. Originally thought it would be fun and would be a feeling of accomplishment of learning how to use the X-01 and perfecting the skill/craft of sharpening my own skates, but since seeing the Sparx sharpener I'm starting to think the ease of use may be more appealing. I also never considered possible dust etc. the X-01 would create until reading about the Sparx air filter/clean up. Leaning towards the Sparx, but just wish it was a little cheaper than $900. Will definitely be keeping up with this thread to see what experiences others have w/ it over the next month.
