Want to Buy WTB: 645 slide mount

I just need one to block the stray light of the light table while copying slides with the digital SLR and macro lens. Anyone in the USA got one to spare? I can pay with Paypal , check,or MO. Thanks.

If you don't find one closer (I'm in Canada), send me your address by PM and I'll drop one in the mail for you - no charge .
