I have 4 classic Macs available for the taking. Shipment should not be a problem, if you're willing to cover the carrier cost, and a few bucks for a can of spray foam. Standard USPS shipping to the continental U.S. is between $30 and $40, depending upon destination. That includes tracking, but no insurance.
All of the machines have seen some action, but I would describe them as more towards "good" than "fair," but definitely not pristine. I can send detailed pictures of specific machines if you're interested. Here's the list with some specs:
UPDATE 1: 3 of the 4 machines are gone. The Beige G3 is still available if someone wants to pay the shipping, which I would estimate to be about $45 in the continental U.S. I'm in the midwest and just shipped the G4, with $150 insurance to California for $40. The G3 is about 4 lbs heavier, so it will be just a bit more. Oh, and using spray foam as packing agent turns out to be a crappy idea.
UPDATE 2: I went ahead and listed the beige G3 on eBay:

Wow! It sold 75 minutes after being listed.

This machine was apparently exposed to a damp environment at on point, because the external PCI slots show some corrosion. The inside is clean, however.

There is a crack in the plastic side panel on this machine, from one of the hex mounting bolts to the corner. The defect is only cosmetic, and does not compromise the structural integrity of the case.

There's a source on eBay that's selling slot-loader CD-ROMs for less than $13. I would be happy to install one in this iMac if you buy the part.
