I use the 55IR as well. Bought it because someone was smashing my mailbox, and I wanted to catch whoever it was. (Country living at it's best lol) I used it this past spring for turkey scouting, and will be setting it out for deer in another month or so. Easy to use, good quality pics, and a very nice price. I got mine at Sportsmansguide.com as well. I think I paid $70-80 each for them. Haven't found anything so far that I don't like about them.
