Ever since I learned to spin last year I have wanted one of these. I keep looking at them on ebay and saying I am going to get them and then don't end up doing it. Why, you might ask? Well for one thing I hate to pay the huge shipping cost to send this thing to Canada. I mean the blockers themselves are $26 US and then to pay an additional $17.30 US to send them to Canada I think it's nuts and highway robbery, to tell you the truth. I will be in NYC next month and the bug is itching me once again to order them. We'll see how long I can resist this time.
