I bought BobCAD-CAM V25 4-Axis Standard near the end of it's service life for a total of around £1200.
For the price it's fantastic and was the step change in functionality compared to previous versions they needed, the opportunity to run trials of the versions up to 29 has been very useful.

If I were you I'd go for the free to small users Autodesk product, it's fantastic value right up to the point they pull the plug and hand you a bill for your next 12 months functionality, although I'm sure Autodesk would never do something like that to free users in the way they've tried to do it to Perpetual Licence users! :D
