I bought an Elliptical trainer, I found a Proform 1280s on Craigslist for $400. It’s not in perfect shape, but it works. I managed to do a 15 minute session on Sunday and again this morning, and the sweat did flow and there is much soreness in my legulons. Exactly what I wanted. The $100 and untold carbon-footieprints I saved over buying the Schwinn will go toward saving the planet (and/or bicycle parts. Probably more of the cash will go to bike parts as nobody takes carbon credits.)
Next thing to save up for? MSI Wind or Asus EeePC 901. Whichever Atom-based ultra portable hits retail first.
