What are some highly reviewed Singer knitting machines?

Some highly reviewed Singer knitting machines include the 700 Memo-Matic and a Singer Knitting Machine for children. Sheepishly Sharing states that the child's machine is a huge improvement on Singer's previous children's machine, which they claim in comparison was difficult to hold still.

Singer no longer makes adult knitting machines, and those interested can only buy the 700 Memo-Matic second-hand. However, the Studio Alexander website states that it is a wonderful machine. It may need replacement parts, but it says buyers can purchase these relatively easily. In addition, Machine Knitting Advice claims that singer technicians still provide service for its old knitting machines.
