The rings I got from amazon a little while ago for like 35. Just checked but I think they might be sold out rn. https://www.amazon.com/dp/B088HJTY6K/ref=cm_sw_r_cp_api_i_fK.dFbNZQNJSX
The rack is the basic fitness reality 810 XLT, I found it on Overstock for like ~$260, so I snagged it real quick before it quickly got sold out.
