Tax Write-off for darkroom equipment

[iwingfield]

I am going to be working with a small South Carolina public elementary school this summer, and they are trying to get a darkroom started. It will be used to start a program teaching kids photography and photojournalism (This summer they'll be documenting their community). I am looking for donations of darkroom equipment to help them get started as cheaply as possible, so there will be more money for film and paper (The school will be buying supplies since the kids can't afford it). Shipping will be reimbursed and you will get a tax write-off for the value of the equipment you donate. Any suggestions about getting started would also be really appreciated. Thanks...
