The 8UAP is a good radio and it only came as a narrow band unit. It's also a limited computer radio and is capable of straight FM or PCM use. MANY are still in use. In other words it is a nice little radio if you are sure you will stay with Futaba 72 MHz radios. As to the value, it's hard for me to say.
The synthesizer itself

is worth @$90. You can also put Spektrums 2.4 GHz modules in it later if you want to.

I can't recall how many model memories it has but you can look up the manual in Futaba's site. www.futaba-rc.com

It's not a GREAT buy but not a bad one either IMO depending on things mentioned above.
