These were the top of the line in their day and I think they are still way on the top. The needle was made on a slant which moved it about an inch forward so you can see what you are doing and less strain on your neck. They are made out of metal instead of plastic. There is plenty of stitch selection. They are fairly easy to maintain. You can find them in thrift stores occasionally, ebay or CL for about $150 plus or minus - fairly good price considering they were $500 - $600 when they were new - and it's been a while. Worth every penny if you can find one in good shape or one that has been refurbished.
