I have a remington ghost, which is the same camera as the WG. Pic quality is decent but the trigger speed is a little slow.
I use the Wildgame Innovations 1.3MP and its great, The quality is awesome and have had no issues with it.
If you are looking at the $50 one at walmart, there is a 3 page thread on AT about it. They spell out ways to get longer battery life, and ways to tweak it. Another plus is, if it get stolen you aren't out much.
