I've been researching them also. What I have found for differences from looking at the specs on each are that they are the same machine, but the 2010 is a newer model. The 2010 has these added features:
variable sewing speed control
1/4 quilt foot (in addition to the 1/5 quilt foot)
zipper foot
hemming foot
compensating foot
I was talking with my repair guy and he said that either model is great. The feedback I got on here was that it is reliable and needs little if any service.
I would be happy with either myself. I would base my decision on what deals you can find. The prices are basically the same, but some dealers throw in more perks like bobbins/needles, free shipping.
