okay. so as i said prior i've been looking. todays search the machines come to $600 difference. there are few differences between the machines. one is the 420 (cheaper machine) comes w/table. the big difference which to me is the $600 difference is that if something happens to this machine and needs repair, you box it up and mail it back to brother for repair (dont forget shipping cost). if something happens to the 570 (which was bought in local authorized shop), i bring the machine to them and they (hopefully) repair it. worth the $600 or not? what do you think?
