I got my pro model last Friday, and although I haven't had a chance to use it yet, I'm really impressed with this thing! Talk about a well made and over engineered chunk of sharpening goodness! I went to pick up the box and almost dropped it- wasn't expecting it to be so heavy. Everything in the case is nicely labeled and all the extra stones, etc. are wrapped, the sharpener itself is very well made and looks like it will last two lifetimes. The DVD is very informational and answered all my questions. I'm sure the standard model is well made too, but the pro is over-the-top quality wise and completely adjustable not to mention rock solid. I need to go dull some knives and try this baby out!
