Use the money to buy a kite-surfing rig, it is much more effective at delivering the high you are looking for i.e. a huge smile with enormous lift. Pumps are a joke, however, they will demonstrate to you what is possible under a good PE program. But you will still have to put in the time to get at your hidden penis. To get at whats in that cylinder will require a disciplined technique.
Another approach would be to go to Aspen with your gal and experience a full body pump, approx. 3Hg, @ elev. 8000, your gal will love the new you and all for the price of a fancy “left coast” tube.
