Asking for $15.0 with First class mail shipped

By the way, this RX should be compatible with the new Spektrum DSMX TX, if the following link is correct.

Should I purchase the DSMX add-on?

Before investing in the DSMX transmitter add-on, there are several important facts about DSMX you need to know:

* To realize the full benefits you must have both a DSMX Transmitter and a DSMX Receiver
* DSM2 transmitters are compatible with DSMX receivers. Likewise, should you purchase a DSMX transmitter add-on, the DSM2 receivers you have now will be compatible with it.
* Because DSM2 and DSMX share the same wide-band DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both.
* The difference a DSMX system makes is only apparent when hundreds of 2.4GHz systems are in use at once.* DSM2 users who rarely, if ever, fly in big events or other exceptionally "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need.

*A DSMX system refers to a DSMX transmitter in use with a DSMX receiver.
