Delta isn't the only one with variable speed. Jet has a 10x14 with it and so do most other manufacturers also. not sure about the reverse.I've got a Jet mini lathe, not sure what model, but it works well for what I use it for. I got it used from a guy who needed money so couldn't turn down the price he was asking. That said, if I was going to buy a new one I would go with the Delta mini lathe becuase it has a variable speed knob vice having to move the belts to adjust the speeds. Also, it has a reverse function. Not sure on the price comparison but there's my 2 cents worth..
My 2 cents. I have both jet 10x14 and the 12x20, both lathe has been a joy to own and used on a daily basis. You may want to consider the manufactory support team,jet is great.is it a good lathe?
