I had originally intended to buy a machine from Newegg or TigerDirect, but ended up finding that eBay's search methods were far easier, and I was able to drill down through thousands of choices pretty quickly.
Next step is to spend some time refining a CSS file I'd been working on for a small cash-stream project. I can always get fancier later, when it's up and running.
Today's the last day I can drive the CRX. I'm intentionally letting the inspection lapse. I'm keeping the insurance for now, in case a potential buyer screws up while test driving it.
