I have to disagree with your statement that "they all work the same". This is not true, I've gone from real cheap radar detectors all the way to the best, and they do vary quite a bit. My first one (cant remember the name) did a ok job, for most things infront, however it couldn't tell the difference between true radar signatures and false ones. Also couldn't pickup signals from behind, and minimal laser detection, but 15 years ago, laser was non existent. The second one I got I believe it was a cobra for $130 I think, and it had better 360* protection, but didn't have that great of range. I looked at bell and escort, I believe escort is the second best now or it was when I bought the best: "Valentine 1". And IMO and many others, it is just that, the best. I've picked up signals almost a mile away and around bends and down in valleys. Its also nice to know how many are waiting for you. The only downside I've found with it is having to send it in for upgrading the software, it would be nice just to have a micro USB port and be able to upgrade it at home.
