I recently purchased a PS3 and I love watching blu-ray discs (my collection is getting slowly bigger too

). Anyway I wanted to purchase an external optical drive that can read blu-ray discs, but it seems really complicated, especially for a layperson like me. The thing that troubles me most is that blu-ray gets upgraded -- will the optical drive be able to keep up with these upgrades (like the PS3 can download upgrades by itself)? I wanted something that could read blu-ray discs and also rip blu-ray discs. I found some stuff on this website and I was wondering if they were any good:
LG GGW-H20L External USB 2.0 Super Multi Blue Blu-Ray Rewriter, HD DVD-ROM Drive, Dual Layer DVD±RW for Mac or PC -- $289.95Pioneer BDR-203BK External USB 2.0 Blu-ray Dual Layer DVD±RW for Mac or PC -- $334.95Is there a huge difference between the two? Which one should I get? +_+;
I was looking at this store because it has google checkout. I'd very much prefer websites that support google checkout (if suggestions are to be made, I mean). Thank you in advance!
