I also wanted a Troy Lite Barbell but like elsie3 says the shipping cost was expensive, so instead I bought a CAP Barbell from Dunham's. It comes with 100 lbs of weight, the price was $44.99 and with a 20% off coupon it came to around $36.00.
I believe Cathe used a CAP Barbell with Lower Body Pyramid, at least when I was watching the credits it said CAP Barbell and it looks just like the one I have.
