i have a singer athena electronic machine and not real happy with it as have had some problems. i have taken it in twice because feed dogs will not stay adjusted and are too low, therefore not assisting with feeding fabric thru - usually have to give the fabric a pull thru manually. also, the needle threader worked at first and now only off and on - have to have the needle at just the right place and some threads do not seem to feed thru it. machine RUNS fine, just these little irritating things.
