I just scored a Merkur HD for $18 at the Atlanta Barber Supply store! This is my first safety razor and I'm as nervous as I am excited. Also picked up some blades and a few pucks of soap.
If anyone is in Atlanta I'd recommend checking it out. It's totally old school. They have everything you could think of and run by really nice people. $18 is by far the best price I've seen for the HD.
Not sure what they charge for shipping but here's their site:
Wish me luck on my first DE shave.
