If it's working fine now, make sure you clean the lines after you use it (warm Yager sitting in the lines turns to glue pretty quick). Also, don't turn on the refrigeration with water in the lines.
Theres about 6 in my local Tampa CL that are all at 175.. so id say 125 would bring it home around here. I got mine in a trade for a decent laptop I didnt use anymore that was worth about 100 bucks.
