Knowing your budget is important. My traveling machine right now is my little Europro. My husband bought it for me from HSN. It has a few stitches, has the acrylic table to go with it and is very light weight. It is in a case with wheels from Joann's that I got on sale. It gets used about 3 times a year so I can't say it is a work horse but it travels well. I also have 2 FW machines. They work very well, only straight stitch (both of them have reverse) but when I travel I don't need a lot of stitches.
My Europro cost about $110.00 after tax, shipping & handling. My little VW's were $180 to $300.00. There is a cute Janome Gem that I was looking at but finally decided I didn't need it. My sister has the Brother quilting machine she got at Costco - it comes with the extended table - she loves it and has had it for years! She took it to classes until I gave her a FW.
