Why pay $198 for a ASIC USB 300 MH/s? Why pay $70 for a used ASIC USB 336 MH/s? Get a new ASIC USB Block Erupter 336 MH/s in Canada for $69.99 + shipping.

I was just shopping around on Amazon.ca and I found an ASICMINER Sapphire Block Erupter USB selling for $70 Canadian + about $13 shipping & handling. Currently one of these units will profit about $45.52 a year, so one unit will pay itself off in 1.8 years if you're not paying a power bill.
