Sheldon, the screens plug into the 43 instead of the 35, the 43 plugs into the laptop with a serial cable, that's the only difference in the hook up.
The 43 basically adds is a file system to organize and store test data as you test.
The option to plug in a strain gage as well as the acoustic target is there if you want to use it too. Anyone considering wanting these additional feature down the road might look at investing the money in the 43 they would have into the 35P is all, if you already have a laptop this is even better.
Alot of people just are not interested in the 43, some dream of one. Considering you already have a laptop, a big investment itself, and computer work isn't exactly new to you, I figured I'd point out some of the features and setup of both and you'd see what intersted you.
Here is a link to a photo album I have, it shows how my filing system is set up and organized, there's a pic or two in another album there too of the actual test screen. You might be interested in one down the road...
