I paid $125+ shipping for my DaLan on ebay, total was $152 with shipping, and it came with a nice 2" ball too, and cables and light box converter (separate brake/signals to single for a trailer) pretty cool. I've been enjoying it with my bike carrier, waaay better than a strap on one. I need to try actually towing something though, maybe my girlfriend's dad's popup trailer sometime soon.

Here's mine on my beastly 300SD
