That sounds like a great deal, would love to see how it works out. There's a few rebranded large capacity Lexar cards finding their way onto ebay that are well known to give regular data errors but I dont think there's any affected 8GB cards.

I'm using 1GB cards and a 20GB portable hard drive with a card reader. With the D200 I get 60 RAW files onto a 1GB card and I've started forcing myself to edit the photos heavily before transfering to the hard drive or the laptop. With RAW files you can pull or push half a stop easily with virtually no effect on image quality so I only bracket occasionally and only if there's more than a stop either way. The D200 (and D70) meter is usually very accurate and predictable and I usually underexpose by 1/3 stop as a rule to ensure nice deep colours, helps being able to hand hold as well which is great 'cos I hate tripods with a passion!
