Cut the hose, insert tank made of PVC tubing, with an out going valve.
Charge the tank.
Put blow nozzle in end of hose (mine came with two), open valve.

Cheap, yes.
Effective maybe, depends on your needs.

You left out "dangerous". PVC for compressed air use it known
to produce shrapnel from time to time -- mostly when you don't expect
it.

Enjoy,
