Best - My EZ kut (http://www.woodyhunting.com/Package-Offers.html) for $40 at a trade show.....I thought it wouldn't last me more than 2 trees of drilling. Works great for hunting on public land where you gotta carry your ladders in and out constantly when hunting a non-climber spot.

Worst- I wish I knew the name of it...a $4 grunt call. You get what you pay for...froze up every time the weather dipped below 32...replaced it with a primos buck grunt, I'm looking forward to trying the new one out.
