Medecos, Diebold 177, S&G 8077AD for trade or sale!
I've already double checked ebay to make sure my prices are at least 20% cheaper than the best offer (as of 5/26), though if you find a cheaper ebay offering, email it to me and I'll see what I can do.
Medeco original KIK, 6 pin + keys: $12 (The original is like the biaxial, with rotatable pins, and generally has 2 top mushrooms.)
Medeco original KIK, 5 pins + key: $10 (Easier keying, good to start learning on.)
Medeco Cam lock + key: $10 (Some people consider these to actually be tougher as you have to rotate and lift simultaneously.)
Medeco Cam locks, no key: $5 each.
Sargent 6 pin cylinder + keys: $12 (Tight tolerances, excellent challenge.)
Sargent 8077AD: $25
Diebold 177, premounted + stand: $30
Continental U.S. shipping will be a small flat rate box ($5.80) if buying the smaller locks. If you buy the Diebold, shipping will be a bit more (~$10), but I'll cram as many locks into the box as you'd like as well. Basically, I'll get you the cheapest shipping possible. I will do international shipping, but will need to discuss more in depth on an individual basis first.
Cheers,
