what version of vmware is right for me?

firstly it has to be either free or cheap (under say 70 dollars)

and secondly it has to support both Windows and GNU/Linux, optionally FreeBSD as guest OSs

the host archetecture will be amd64 and i expect the guests to also be amd64.

the plan:

i've dual booted, tri booted, even quad booted but its a pain in the butt to reboot everytime. i've messed with VirtualBox but its just not powerful enough yet. and i saw a video where they had the compiz cube set up with each side a diffrent instance of a virtual machine.

this is pretty much what i want/need but i'm very very unfamlilure with VMware and all these diffrent versions sound very simular and really the documentation is just trying to sell that particular version not really give any solid pros and cons.

basically this is for a workstation not a server.
