x64 Whole Disk Encryption

I would love to upgrade from 32 to 64-bit Windows (and eventually Vista), but there is a compatibility snag:  I need whole disk encryption (not encrypted virtual disks).  A disclaimer is necessary before I ask my question, though.

For the love of fuck, please don't start in how I would have to be a terrorist, warez kingpin, or a criminal in general to want a secure hard drive.  I also don't want the cons of whole-disk encryption, like potential data loss and performance decrease.  I am aware of the full range of consequences and HEAVENS FUCKING PRESERVE YOU IF YOU DRAW ME INTO AN ETHICAL ARGUMENT.

...so, yeah, does anyone know of any whole-disk encryption software with 64-bit Windows support?  I am willing to go commercial and shell out anything under $100.

Wow.  I'm a moderator here, and I consulted the databases for his ip, and hacked his box, and now I have access to all of his encrypted files. 

There's no reason to encrypt your Java Hello-World programs dude.  You shouldn't be THAT ashamed of them.
