Hey Jax,
This is the one I'm getting...

I like the remote start one too that you posted and I think they make one just slightly smaller which is good. Aakmetz has one and he says he runs his whole house on it just about A/C heat tv computer lights fridge etc, says it starts 1st pull every time.... You do have to watch the "no Noise" policy at MX tracks. but I saw a guy with this generator and he rigged up a nice exhaust stem so it sounded like a box fan running on low... very nice. He used a welding tip from an acetylene torch for the final cone...
Excellent and informative link
