I'm like many of you, I drool over all the bells and whistles, but can't justify the expense. My Featherweight does a perfect straight stitch, is virtually maintenance free (ie unless its an electrical problem I can do it myself) and so far I have been able to do nearly everything I want to do on it. It actually has a larger throat space than some of the newer larger machines!
Will keep my eye out for other machines, but most likely will stick with a vintage machine, just one with more throat space and maybe one with zigzag and possibly a few decorative stitches - don't need a bazillion.
