Roadmorph comes with a mount that you attach to the frame wherever you want- whever it doesn't interfere with waterbottles, etc. I put mine on the top tube. The downside of this is I have to remove the pump to put it in my bike rack for transport, but this is very easy, it just clicks in and out. It's small enough to carry in a Camelback, too.

Roadmorph easily inflates to the 90psi range. You can go higher with a little effort. It has a built-in gauge. Right now I am running my tires at 95psi after reading the tire pressure article, which there is a link to in the equipment section, I think.
