I can pick these up pretty cheap on the secondary market here, pawn shops, craigslist, etc. I only want to buy one computer so I want to make sure one of these will wok. Any suggestions?
Chomebooks are great, but they have very defined purposes. In your position, I would likely buy a Windows laptop. This time of year there are plenty of good deals around. A good place to start is: Computers Deals, Sales, Coupons & Discounts
These little laptops do a great job running UGS. They take up little room in the shop are turn on almost instantly when you open the lid. Plus it has built in WiFi. For under $150 on eBay its tough to beat as a dedicated gcode sender.
Again, I do not use Easel. But, I get all my cnc machines out of the dumpster. Sometimes I spend $90 on a new Windows 7 license… but usually can salvage the key code using BelArc Advisor and then reinstall its operating system fresh and clean. For a shop machine I try not to spend any money.
