You might want to consider buying a small compressor rather than renting. A pancake compressor can be quite useful to have around the house. You could also buy a stapler that converts to a regular stapler/nailer for general use (example
A little compressor and an 18-gauge brad nailer makes putting up trim easy and quick, so it would be money well-spent.
Honestly, though, I've found nail-down installations to be just as easy as floating laminate or click-together flooring.
To answer your question, thin tongue-and-groove engineered wood is glued together to float it. I'd look at a sound-deadening underlayment so the floor doesn't sound hollow.
Can you see how the existing flooring is installed?
