I have the PQ1500s (Nouvelle). I bought it used from someone whowas selling it on eBay. I love it for both piecing ad fmq. Ikve had it for several years now and find it very easy to maintain. It’s not picky about thread and has sewn through every thing I’ve tried with no problem. It’s a real workhorse. The only drawback for me is that the needle threader is finicky so sometimes it takes me several attempts to get it to thread the needle.
