I know this is off topic but it seems many of you have experience with the assortment of wireless choices out there.

I have a couple of Xstream X24009 OEM modules that I'm using right now and they're very impressive, good range and very reliable. Also, I think these are FCC approved right out of the box which is a plus for me.

BUT--

They're pretty pricey -- 100 bucks each

Does anyone have any other manufacturers with modules like these that are FCC approved at a lower cost?

I'll probably go with 900mhz for more range -- I need LONG range for industrial environments just to transfer RS485 data.

Thanks !
