I reworded the page to make things more clear and reworked the kit options to include the Sherline 3701 right angle plate. That made more sense to be able to get your choice of kit depending on machine/mount type. The difference in kits now is the type of mounting plate and both are a little less than buying the parts seperatly.
The Taig kit comes with the rotary table, Sherline tailstock, a 3/8" mounting plate that I manufacture, stepper motor, and stepper motor cable. Since the plate is pretty thick I have not found that the right angle bracket is needed.
The Sherline kit uses the Sherline 3701 right angle mounting bracket instead of the mounting plate I make (so it is a bit more expensive).
Anyhow, I hope that helps. If the Sherline table will do the job for you then I think you will be very pleased.
