This is a pretty new system, just catching on. IMO, that price is a fair but not great sale for the present time. There are a lot of names regged around this term (like GPSfarm.com, farmerGPS.com, GPSfarmMap.com, etc.)...
But remember that you have the category killer, here. All those people would like to own GPSfarming.com. My 2 cents: if you can really use the cash, it's not a poor price, it's quite fair... but if you can afford to wait awhile, I wouldn't be in a hurry to sell. This looks well on its way to becoming a standard in the industry, and if I owned that name I think I'd either hold out for a minimum of $4K, or wait for another few years to see where it goes... maybe by then it'll be a 10K name, especially for manufacturers that specialize in making GPS for farming?
I have a few forward-thinking names like this that are category killers in their respective genres; and the whole idea for my getting them was to keep each one for a few years and see where that tech ended up, not sell cheap in the beginning when that tech is just starting to be recognized. It's a gamble, but if you have a few dozen such names for a few years, all you need is one great sale to make it worth it. Yours is the kind of name that I would sell for a bigger price right now than 2K, would leave until a bigger offer came along.
Up to you, but that's my thought.
