I would still buy the FM800, however did want to agree with a previous post on the HSL and law enforcement concerns. I too live in a suburan area. Have several friends who are in law enforcement, they tend to get calls for everything under the sun. If someone saw me waving my receiver in a field it could easily be viewed as a cross-bow from a distance or if someone saw you pointing it out a car window it could be mistaken. Perhaps for future consideration you could offer the option of a bright orange yagi? I work for a manufacturing facility so I know that sounds easier than actually done but just a thought. Also, from a marketing perspective a bright orange color would distinguish a Marshall receiver from others the in field (just my opinion).

Looks like the FM800 is going to be a hit regardless!
