The current batch of (about) $40 units are different from what was available a year ago. These new ones require 5V DC input in addition to 15V and can only be programmed via RS232 a few Hz away from 10MHz. So they are only good for use as a 10MHz reference
"Option 2" in the book refers to a different type FE5380 that can be programed over a very wide range of several MHz. I think these are still being sold on eBay but not for $40. They seem to be over $100. Which is which and how to tell? Just look at the price.
