I use the gauge I bought from Randy at Watcom
The Rad routinely changes 4-5 points where I live (even with the temperature bing the same) - by using the gauge I can determine if it is my latest mod that is slowing me down or if it is just the air. I record the Rad everytime I ride.
Other items I use of Randy's
- impeller gage
- marine grease
- piston inspection light
- leak down test kit
He has all sorts of hard to find items on his site

Really you need a air sampler/weather analyzer for quick accurate density altitude numbers. The formulas are fine but you still need accurate data to plug in to the formula. Air samplers are the only way to go. If you are serious about performance mods and knowing what works and what doesn't, then an air sampler is a must. Plus like Phillip_GPR said you need to check you air after any tuning or parts change to keep a baseline.

www.Accuweather.com has hour by hour data updates. Works fine for any part testing for the rec riding I do.
Here is a site below that sells portable weather stations/samplers that are easy to carry and affordable
The Kestrel 4000 Pocket Weather Tracker seems to do it all.
