All the above comments. I really like mine to take to classes and sew ins. I never have any problem as some of the newer computer machines seem to not like to travel as well.
JLM is correct that you can do a ton of neat things with the attachments. I don't have one but I even hear that there is a zig zag attachment.
I sewed on mine for 6 hours straight on Saturday guild sew-in with no problems other then having to refill bobbins.
If you decide to sell it, you will not have a problem finding a buyer.
