Air bag pump difference.

[Zumo]

Why are the pumps sp expensive? What is the difference in these pictured?

This one is about 40 bucks



This one sells for 200 bucks




Funny thing is these pumps look like pumps we used to replace in high capacity laser printers and mail machines. I had 2 of these laying around and I should have kept them. Don't they all just blow air? What's the deal?

I find this to be the most expensive part and I am on a super tigh t budget. I think I could wire one of those car tire pump to work fo me.
