I have played around with many single board computers. I sold several on ebay last year. I would recommend looking into one of the industrial boards like PC104, one manufacturer that has very good prices is Advantech http://www.advantech.com/ There are also very good deals on similar boards selling on ebay quite regularly, for example I've seen some sell as low as $30, and I sold one that was a 1Ghz PC104 with 512MB ram, a dual PCMCIA add on card, a PCMCIA wireless card, all cables and accessories, and I sold it for $199, it was worth much more new but I needed to get rid of stuff that wasn't being used. It was a nice setup but too power hungry for my projects. I used to do a lot of work on PC compatible small boards usually in the 6x4 inch format, but now I'm working on ARM based boards, with more specialized purposed, mainly due to their much lower power consumption for battery operation. Set up automated searches on ebay for keywords PC104, PC/104 and Single Board Computer and watch for a while, you'll see some really good deals. -- Doug
