Query: NOT a good machine

I am mystified by the 4 and 5 star ratings this machine has received. I myself have had nothing but problems. I followed instructions and used only singer needles/bobbins. I have spent more time replacing needles, re-threading and fixing tangled-up bobbins than I have spent actually sewing. I finally gave up and purchased a Brother machine that works beautifully. Customer support at Singer was not helpful--tended to blame problems on user error. This I can accept, but I truly believe I have done everything right and that this machine is just a stinker. A shame, Singer used to have a great name and now I will never buy another.
