Paying that much for something is alright depending on what it will be used for, a buisnes is fine, but for someone who wants to just use if for parts runs or something thats to much, I bet students wouldn't mind one, also, heres another intresting fact, wich one will crumble onder the weight of 600lbs? That kit on my bike or my home made kit, I've tested mine and it wouldn't even budge under that weight, for a home built it looks normal and is strong, I'm all in for Extra and those others though, I like them, I just wont pay that much
