Do you mean monolights or strobes? I think the biggest difference is monolights can be plugged right into the wall while strobes must use a power pack.

I have a Hensel monolight and a Dynalight monlight. I like both and they are easy to use and can be easily moved around the house or even outside.

I would suggest maybe one monolight + a softbox and a reflector (which you can easily make). 2 monolights can get pricey. You will also have to have a light meter in order to get the exposure right.

If you already have a flash for your camera you can use that as a fill light as well.
