Read/Write HFS+ Partitions in Windows
I have used MacDrive in the past, but I recently stumbled upon this free method (assuming you have a Mac OS X install disc). Looks good, but I haven't had a chance to test it.
Note: The free method uses the Boot Camp driver in the OS X install disk. It seems to be read-only and for the Intel processor only (i.e., it doesn't work with an AMD-based processor).
MacDrive or HFS for Windows, TransMac are all good options, there is also HFSExplorer - it is free, but only provides read access.
Paragon's HFS solution appears to be the optimal solution in this case; it's free and provides the most features at no cost.

Most of the other options cost around 20 USD...
