have you visited the APQS web site? that is where you will find information...also...
buying a long-arm system is AN INVESTMENT-and a fairly expensive one...you should not buy one just because you read something good about it...you need to try out as many long-arm as you can find and make an educated decision. just because i love my machine does not automatically mean it is the machine for you. would you buy a car or a house without looking/trying out many? i hope not
and why has the woman only used the machine a few times in 5 years? does she have problems with it? like tension issues?
it might be important to know why she is selling it. doesn't sound like she's just up-grading, there must be a reason.
before making such a HUGE commitment you really need to do LOTS OF HOMEWORK
good luck :thumbup:
