I have the PQ1500 and like it. It isn't that old but I had to take it in b/c the shuttle mechanism inside the machine filled up with lint. I have quilted so many double- & queen-size tops so I guess the lint built up fast. I had at least 25 tops waiting to be quilted and was overwhelmed as my small machine made quilting large tops so difficult. The throat area was the reason I bought the 1500 and I do not regret it. Quilt tops got quilted in record time. The machine takes a bit of getting used to but once that's down, it's full steam ahead...at least it was for me.
