I am not sure about the pins I believe they are the same.
As far as them being cheap and underrated, there is a reason for that. The radio has a known flaw and a serious one at that. The radio will randomly put out a long "0" DTMF tone on channel one. There is no warning and the user has no indication of the transmission.
This is just something to note, I do not know if there is a fix out there for this or if there is a newer version that this has been fixed in.
