Oh wow that's way cheaper. For SP it's 10x as much. I may actually do this then, though laser etching is considerable less pretty than dye sub or double shot.
The reason is, you're probably asking SP to make custom doubleshots, which is $45 per mold IIRC, and then they have a pricing tier starting at $20 each for five, down to $.41 each for 1000.
WASD will do you a small run, but the laser is a much different quality than you can get with doubleshots.

You might be able to get someone to help you do a GB for these if you want to get the SP ones at a decent price.
