RE: roll cage
heres a link to the ebay store of he seller whom i bought mine from, i thing i got mine for like 20 bucks it's the steel/chrome one,it was aparently a "scratch and ding" cage,, but i didnt find a mark on it,, it's very light, and does a great job of protecting.
they also sell them in stanless steel, but i would guess they would weight more
