Does anyone have advice on a reasonably priced external PCI-E X16 expansion box? The ones I could locate thru Google cost more than a new computer. I only have one slott for the time being, and I don't think I will be buying a new computer anytime this year (my car's transmission just went out).

I'm not an expert on this, but others have indicated it is better to get a new motherboard that supports multiple cards (maybe MSI Z77A-G45 @ about $100?) than an expansion box.  You can use a single graphics card for rendering and Windows display - it just means Windows runs a little slowly when rendering heavy scenes.  You can also use you on-board graphics for Windows display and the graphics card for rendering (my current setup) and they works very well.  The best way to check is to run the demo version of the plugin and see how you current system performs.
