Wait for Llano? The IGP on Llano has 3D support. Right now, Sandy Bridge is the only IGP that has 3D support but I'm not sure if you can consider that cheap. For the same price as H67 MB/i3-2100, you can get 880G MB/Athlon II X2/HD 6450 or GT 520.
Seriously, though, if it's only for disc playback, an actual Blu-ray player would probably cost less and have less issues.
