Bill,
You should have started with me. I install broadcast audio for a living. The Tascam devices you are looking at on Ebay are really old, they are wrapped around a cassette recorder that in some models was confiqured as a four track device, only one side of the cassette. Depending on what you budget is, Mackie makes great little boards that have headphone outputs and lot's of features like solo and sub-mixing. Behringer also makes some great gear as well. I would recommend you check out Muscian's Friend, Sweewater or Full Compass. They all sell stuff for computer audio and there are many USB control surfaces that will turn you laptop into a powerful post production surface. There is one device from Digidesign that has two mic pre amps, and two line inputs and comes with ProTools software for I think about $400. Anything you might want is out there, and new is way better than used unless you know exactly what you want.
