More Newbie questions from a guy!

A couple of days ago I posted a question as to whether or not a $40
Sewing Genie was any good. All said it was junk and suggested I go to
a sewing shop and look for a used machine. I am confused as I don't
know what to look for.

I am a male who needs a small machine to hem seams and easy stuff. I
don't know anything at this point, not even the proper way to drop in
a bobber and my space is very limited. That is why I hoped this Sewing
Genie would be good.

Would someone please explain what I should look for, what questions to
ask and any model to stay away from? I saw where Singer has a tiny
machine and I thought with the name, Singer, it might be good. A lady
friend said to make sure I get something that does reverse stitch. I
am lost.

I do appreciate any help you give and will give in the future.

Thanks,
Mark
