I received an inexpensive Singer as a gift from my boyfriend, and was very unhappy with it. The presser foot was not capable of raising higher than it's factory set height, which made it impossible to sew thicknesses (like when hemming over a seam) that were not even unusually thick at all. Then, when I tried to make buttonholes, I had much trouble before finally realizing there must be something wrong with the machine. I returned it to Hancock Fabrics, they agreed it was malfunctioning, and suggested a machine made by New Home. I have never been happier! Had never heard of the brand, but I guess it has been around a very long time. I had to pay more, but with something like a sewing machine, that you will use for many years, you get what you pay for, and time free of frustration and annoyance is pricelss. I've been sewing for 30 years and still use the same pair of fabric shears that my mother bought me that many years ago! They cost her $40 back then, which was alot for a pair of scissors! They have never touched a piece of paper - only fabric and pattern tissue. By the way, I also had a $99.00 Brother, used it for maybe a month, accidentally hit a pin with the needle. A good machine will just break the needle (no big deal), but the Brother suffered fatal damage. The wheel could only be turned by hand, and something deep in the workings clunked with every revolution.
My best advice is to be prepared to spend as much as your budget can handle, and then get recommendations from those who do alot of sewing - start with fabric store employees, before making your final brand choice.
