The Castle Creations Berg receiver is a fine receiver, but it's $9 more than the Tower receiver, not $1 or $2 more. The Futaba and Berg receivers don't come with a crystal, you must purchase that separately. The Tower receiver does come with a crystal.

You need the following crystal with the Berg:

If size & weight were an issue for me, I'd probably pay the extra $$$ and get the Berg.
