This afternoon I made a mistake and went snooping on eBay. Long and short of it is that I accidentally ended up with a nice looking D300 for less than I can sell my current D200 for. However, it doesn't have an accessory grip, which I've really gotten used to on my D200. I started snooping eBay again and I see all these aftermarket grips for considerably less than the Nikon grip.

Has anyone ever used one of the aftermarket grips and are they worth a spit? Any chance of the tripod mount screw pulling out or something else goofy? Or just pony up the bucks for the genuine Nikon unit? Bear in mind that I'm a light camera user these days....

Thanks for any info.
