Jeremy,
The Bluray readers, with the capability to "burn" CD's and DVD's are in the $50 range (some even cheaper).
For the Bluray "burners" there are diverse options, quality and prices. Even compatibility based upon the quality of the video card within your computer, however my own interest is not in utilizing the Bluray video at all. Rather the expanded data storage capability.
MEI Microcenter seems to offer a variety.
