Taig CNC or Sherline CNC?

I'd like to hear opinions/experiences with Taig and Sherline CNC mills.
I'm trying to decide which one to purchase. The Taig machine looks to be
built a bit heavier than the Sherline, but the Sherline has more
horsepower and lower spindle speeds. Can the Taig CNC be run ith EMC
rather than the DOS software that comes with it? The Taig appears to
have higher torque steppers. Sherline has variable speed control while
Taig appears to have step pulleys.

Help!!
Thanks!
