Just to be clearer, the OT.com policy is that you need to own legally the retail version from which the fanedit was sourced. So, to download ANH:R, you don't necessarily need to own the Blu-ray; owning the DVD version will do. However, once ESB:R is released, you will need to own the Blu-ray of ESB in order to download it (since it's Blu-ray sourced, unlike ANH:R in its current state).

Repeating this, because it needs to be repeated. I'm sure the Blu-rays will start cropping up used for a decent price soon. I got mine from a going-out-of-business Blockbuster Video for $10 a movie. Unfortunately, they didn't have ANH, so I'm still on the lookout for it.
