Buying Evil Genius pre-patched

I'm hoping to buy Evil Genius, but I remember there being two patches (official and unoffical), each which only worked with some versions. Does anyone know where I can get a copy that's pre-patched or works with whichever patch is better?

GOG.com's release comes pre-patched to 1.01. I successfully applied the unofficial patch to it without issue and completed the game with it.

There has been some confusion regarding the GOG.com version actually being 1.01. However, GOG.com contacted Rebellion who confirmed that it is indeed 1.01. There are more details on this in the linked thread.

The Steam version has a patch available through their forums.

*This patch contains the following things:

• All the files you would need from both the official US and EU Patch, carefully hand-picked and tested for use in the Steam version (also see: Readme.txt).
• Contents of the freely available Bonus CD, which is not included in the Steam version.
• Unofficial Patch 1.2, which was originally made for the non-Steam version (also see: Unofficial Patch 1.2.txt).*
