It is virtually identical to the NX-400 Pacesetter that I purchased in 2003 and was at the time, the upper middle of the Brother sewing only machines. It has been a reliable and strong performer and very much still in use today. It requires only minimal maintenance, a synthetic grease on gears every year or two depending on usage. The service manual is available and the process isn't difficult, but taking the outer shell off can be a bit intimidating the first time.
