the old non reverse 99s are delightful to sew with. tensions are simple to service. Some times they do need to be rewired. The newer 99s do have reverse and they do have a foot control. The Spartan is a good machine. The plastic cases do die. A simple wooden box can be put together to set the machine in. The machines are good, easy to use and service. A brand new motor, foot control and wiring can be bought new and easily attached to any of them. The FW is much more complicated.
