It's been a long time since I installed a cabinet. Back then there was not much available but a (plugged in) drill, clamps, patience, a strong back, and MUSCLE!
I just came across a great article, Cabinet Installer's Toolbox, by builder/remodeler Mike Guertin, on all the latest tools of the trade in Remodeling Magazine. He even provides us with links to buy them!
You may still decide to go with the old fashioned way; but at least you'll know there IS help out there, if the back, or the patience, gives out.
