Eliminating eBay as a source and using a place such as Amazon (or NewEgg etc. ) what are some recommended best drives currently manufactured and readily available? I just treated myself to a fully maxed out SSD 15" MacBook Pro and now need to buy a drive. How are the Apple external drives? I realize they cost $79 while all others are $20-30 however no big deal.

Is there one currently manufactured (and readily available) drive considered the absolute best?
