Recommendations for a "sturdy" Pull up workstation!

Hi all,

I am after a sturdy pull-up workstation(not door-attached ones). Have been reading reviews about so many of them available online being flimsy and not so sturdy. I've also come across some commercial ones that are priced over a thousand dollars. Has anyone got any recommendation for a good one that won't break the bank?

I know, I can go to a park and use the bars there for free. However, prefer to have one in my home.
BTW I am 85Kg.

Thanks in advance.
