I started with laptops and realized what I need was out of my budget, then moved to desktops and realized the same here as well. I'm just going to have bite the bullet and save more money for what I need. I'm apprehensive about a refurbished computer, I've always thought that a computer was something to buy new.Use a desktop instead of a laptop. Many laptops use the power saving cpu's.
Made a $70 order at mcmaster.com to stock back up on nuts/bolts/washers and threw in a piece of 1/8" delrin to maybe make a better roll bar for my stampede... and other stuff if I can form it a bit.
