+We also fly commercial altimeters in some projects. The cheapest off the
+shelf altimeter we've used and often recommend to beginners is the
+[Missile Works](http://www.missileworks.com/) RRC2-mini. At about $80, it
+gets the job done for simple barometric control of dual deployment. Note
+that while early versions had a firmware bug that we believe is at least
+partially responsible for Bdale's loss of his first L3 project, recent
+versions seem fine. For another $20, the
+[PerfectFlite](http://www.perfectflite.com/)
+[miniAlt/WD](http://www.perfectflite.com/catalog/MAWD.html)
+adds the ability to records the barometric flight altitude profile. Both
+of Bdale's L3 certs flew with one each of these two commercial altimeters,
+and we often use the MAWD as a backup for our
+[TeleMetrum](http://altusmetrum.org/TeleMetrum) units during test flights.
+
+The [BeeLine TX](http://www.bigredbee.com/BeeLine.htm) boards from Big Red
+Bee are radio tracking transmitters that just work. They require an
+[amateur radio](http://www.altusmetrum.org/Radio) license, but we think
+anyone flying big rockets can and should get one of those anyway!

+## Books ##
+
+While a lot of great information is available on the web, there are some paper
+books that we've found very helpful at various stages.

+ may be the best first book on model rocketry. While the focus is on small
+ rockets, the basic principles of static stability and construction covered
+ here are important at all levels of the hobby.

+ covers a lot of material, and is a great resource if you're starting to think
+ about a high power certification and don't have a club nearby, or just like
+ to read about how other people have done things and why.
+
+* [Topics in Advanced Model Rocketry](http://www.apogeerockets.com/topics_advanced_model_rocketry.asp) is definitely not for everyone, as it's heavy on
+ math and isn't a "how to" book at all! But, if you really want to understand
+ what's going on with higher performance models and/or inside the simulation
+ software we use when designing rockets, the material here will take you
+ a long way!
