I bought a Topeak DX Master Blaster about a year and a half ago, and used it about 3 times before this morning when I wanted to use it to replace the air pressure in the rear tire it lost on the way in. I couldn't get the pump to work, and when I called Topeak customer service they told me I needed to buy a rebuild kit. Even when I pointed out the pump was about a year and a half old and had been used a handful of times. Paying $5 to rebuild a $20 pump that only worked a handful of times doesn't appeal to me, I'd rather buy something that's going to work better and last longer. What would you recommend?
