Need help with picking out a good radar laser detector, easy 10 points:)?

So like everyone else I'm sick of getting speeding tickets! The time has come to buy a radar laser detector (preferably one I can order off of Amazon). I looked but there are just so many to chose from & I really don't know very much about them. There are so many different features & "bells & whistles" that I need help picking. I live in Wisconsin if this helps (& can't put it on the dash as they are suppose to be illegal here but every other person has them). I'm willing to pay more for a decent one but not some really expensive "supped" up thing, just the best for the price. Thanks!
