I like fiddling around with benchtop mills alot, could you post a link to pic or website so I can get an idea of which machine you are reffering to? Alot of companies just rebadge imports, if its one I recognize I will def give my opinion.
The little sieg X2 that harbour frieght sells in store for about $400 is a great little benchtop machine. Not to plug my hobby business but you can see a link to the x2 retrofitted to cnc here. http://www.thompsonmachine.net
