I recently purchased the Blackburn Air Tower 5. Using the pump is a dream. Pumping to 65 psi is extremely easy on my hybrid. Pumping to 120 psi on my road bike requires some effort but not to the point that you can barely get the last stroke in, easier than I expected. This is an excellent, high quality pump, you won't be disappointed. I almost bought the Topeake Jow Blow II but went with the Air Tower because of the lifetime warranty.
