I wrote an article for Sport Aviation about three years
ago that you can download at

The radios have changed but the basic facts have not. I've
not turned on a VOR receiver in 3 years. I fly dual GPS with
a total investment of about $200. I give these things away
at my weekend seminars. Given the signup rate for the Santa
Rosa program next weekend, I'll probably give away two of them.
There's no better return on investment than a low-end
Magellan hand held GPS receiver. The AOPA airport directly
makes entry of a new airport location about a 2 minute
trivial task. Since selective access was turned off, my
GPS300 gives altitude in 1 foot increments.
WARNING! Altitud displays can lag considerably behind
true altitude . . . it's harder to calculate and can be
off by several hundred feed after a rapid/large change.
Give it a few minutes to settle down and/or make altitude
changes more sedately and you'll find the readings track
your altimeter very closely.
