Thanks for checking the weight for me, I couldn't find it anywhere. ~15 pounds sounds great for a travel machine. I double checked the ad and the seller said they payed $600 for it originally, so I am wondering if it is really worth $350 after 6 years of use. I think I will try calling the local Baby Lock dealer tomorrow and get their opinion, and maybe ask about a bench check.
The 3160 QDC was also on my radar, but unfortunately it is out of the price range for the secondary machine. It is almost worth spending the extra money to get a new machine with a warranty, but it isn't in the cards right now considering what we spent on my Pfaff a few months ago (hubby is still getting over the sticker shock!). Maybe if I end up using it a lot, I can later justify getting a brand new travel machine.
