Race Boom

Looking for a cheap racing boom or boom that extends to around 220cm or has 210 within its range. Otherwise if anyone has a damaged carbon boom that is that size it is fine too as I can do carbon repairs. Also looking for rdm extension, can have seized pulleys or if carbon I don’t mind if it is cracked to some degree. If you have something let me know, I’m potentially happy to pay if damaged depending on condition and for undamaged gear but on a low budget.
