How much should a rig cost ?

I wanna plan my budget for the next year or two and i am thinking that maybe it’s time get over the Logitech on a old chair setup and get a proper rig since I find myself spending more and more time in iRacing….

I see those nice set ups some people have and I am wondering how much it would cost me to get a reasonable set up….i already upgraded my pc and I am really fan of vr so no triples or pc at the budget

So without that how much you think it would cost do get a proper comfortable cockpit with some decent wheel, pedals etc ?
