What's the best software for a CNC SHOPTASK setup (MILL & LATHE)

Hi,
I am new to this group and just get a brand new shopmaster bridgemill
and a cnc kit from camtronics. I was wondering what was the best
software for a CNC SHOPTASK setup (MILL & LATHE. I use Mastercam V7
for programming.

I want to use BOTH the LATHE and MILL in CNC mode (not at the same
time...)

Please let me know your preferred choice.
Thanks, JAson :)
