Maybe a Casige? There is one for sale in my area, but they are asking 100$ for it. A bit expensive for a chainstitch only machine...
There is very few hand crank for sale in my area; it seems like every portable machine were converted to electric at one point. On ebay I found only listing of 99 with handcrank coming from Great Britain; shipping is expensive!
I was thinking that I may found easier to move a FW from the family table than a 3/4 size; I don't expect my daughter to "sew" for more than 15-20 minutes at her age. Also, I remember reading some members of this forum saying that their children (or grandchildren) were attracted by the size of the FW.
Money is a consideration, but I can ask the grandparents to help; I would prefer them spending their money on a valuable and durable birthday gift instead of buying some junk plastic toy :-)
Still, maybe it would be better to buy a little chainstitch toy sewing machine for now (if I can find one at a decent price).
