3D CAD/CAM - Vector???

I'm looking to get a complete 3d Cad/Cam package software package
that I can go from drawing up a part to outputting G-Code to be fed
into EMC for milling on the Sherline mill.

I have a Sherline 2000 CNC mill with the 4th axis so I'd like to be
able to take advantage of all the features of this unit and the 4th
axis.


I called the folks at Vector XT (IMService???) and it sounds like the
3d Version of Vector CAD/CAM with the 4th Axis add on should do what
I want to do.


What is the experience from those of you veteran users of this
product?


Are there any others that I should consider in a similar or less
price range?
(Ibelieve the Vector CAD/CAM 3D with 4th Axis is approx $930.00)


Thank you
