I just wanted to share something real quick with this thread. I have read all 125 pages of this post and decided to purchase an X01 and end my 15 year hiatus of skate sharpening. A team mate of mine has been sharpening mine and my sons skates with the 100/75 FBV and I love it so much, which is why I decided to purchase the X01. After ordering online, I called Blackstone with some technical questions and spoke with Mark. Mark was extremely helpful, informative and professional and an all around good guy to talk to. After receiving my X01 on Tuesday, there was a slight issue with my order and I called once again and spoke with another representative, I think his name was Liam. Liam as well was extremely helpful and professional and rectified my issue. I can't say enough nice things about Blackstone and the caliber of people that they have working for them. They are truly a stand up company and they have my business from here on out. Their level customer service would be the deciding factor if I was ever on the fence between Blackstone and another company. Lucky for me, I don't ever plan on leaving the FBV so Blackstone is a no-brainer for me.
