200' is pretty good with the amplified modules. I bought a couple of those a few weeks ago, but haven't gotten to testing them as yet. I've been testing RFM12, RFM22, and BTs lately, plus xiveling and twittering from my ethernet shield, LOL. Plus ColorLCD shield today for data display.
I'm cooking up a home automation system, and planning to use the RFM22s at 433 Mhz to get the system off the 2.4G band, since I can pick up 30 routers here. OTOH, one of my links I want transmitting to the car on the other side of the building, so the amped-up nRF2401s might be good for that. Good to hear they're working now.
