What kind of external flash is compatible with Nikon D2H?

I just bought a Nikon D2H 3 days ago, and I don't have an external flash. I was searching the internet for an external flash but a lot came up, and I actually don't know which external flash is compatible with my D2H. I have a friend that has an SB-28 that's for sale for less than $50, it looks good and he said it's in good working condition, couple minor superficial but looks good overall. I was just wondering if the SB-28 will work on my D2H. I've read that wrong external flash can shut your camera completely and you won't be able to turn it on.

If its possible for you to still get your money back on the D2H, take advantage of than and buy a D3000 or D3100. But anyways, I never recommend off-brand flashes (even though I own one… ) Shop here http://shop.nikonusa.com/...D.43898300

The kind that has the name Nikon plastered over it.
