>>>Hi Walt........hope all's well.
Walt's 100% correct, when I had an 8 point cage/halo done in chrome molly I went to Wild Rides in Farmingdale, NJ best around NJ IMO.
Professionally done and top notch and it was like $1,500 if I remember correct, you get what you pay for and as far as safety goes I don't go cheap, fire suppression system went in next and for $500 it's the best $500 you can spend IMO.
Then again it depends how fast you want to go, 9.99 and slower a rollbar will suffice if you want to go quicker then the cage is needed.
Best of luck in your choice.
