The Realistic TRC-57, 457, 458, 459, and the 490 are very hot items.
They are base station radios do both Sidebands, as well as the Standard
AM 40 channels (except for the 57, it does 23) They also have a clock
built in (except for the 458 and 490). They go on eBay for close to
$100. I once saw a 457 go for over $300. If you're not looking for
sideband, then the TRC-30A, 55, 431, 432, 433, 440, 441, 455, 492, or
the 495 would be best. The 55 and 455 both have the clock in it, but
they are the mechanical ones.

Another Popular Item is the Realistic TRC-24C. It's the simple 23
channel mobile radio. They tend to do better in cold weather than the
syn. 40 channel radio. They also sound good, too. The only down side
is that the meters don't work on them.If you still want a 40 channel,
then the 467 or the 503 would be my recommendation.
