Petsafe Wireless Electric Fence. This unit does not have 5 settings, but has 2 settings. I'm asking $150 for Unit on Craigslist, $200 for Unit with extra collar. $125 or $175 respectively for FR members. New the main unit with power cord and collar retails for $280 but can be had for $250, extra collar is $120, lowest I've seen at least.

Bi-Fold Pet Ramp for putting your critters in back. Good for old dogs, lazy dogs, or dogs that want to feel independent when entering and exiting a vehicle. Pretty sure the wife got taken when she bought this. She wanted me to list it for $50, I'll take $40 cause I think that's a fair price.
