Calibration for 64 bit

On my old XP 32 bit LaCie Blue Eye 2 worked great but now I'm running Vista 64 bit and need to find monitor calibration software that does what it says it will without breaking my piggy bank too much.

I've googled and found a lot of junk and opinions but nothing that I can really zero in on.

Any help?

Not directly camera related but indirectly.

My Eye One works on Vista x64 without any problems...

Spyder3 runs on Vista 64 without issues as well.

Thanks for real world input guys.
