Innov8R, you got a great deal on your 2010qi! Must've done a dance when you found it!
As for the bobbins, I'm interested to know what you bought. For that price, I'm guessing they aren't made by Juki ? I ask only because I've seen a few things online that lead me to believe that non-Juki bobbins often don't work well in these machines. I'd love to know which bobbins you bought.
