The reason for T81 price gouging is that they are the only real military pattern semi-rifle left NR. Another one is G36 but they are 7K.
I was laughing my ass off when T81s were 1K compared to 1.2K CSA Vz58s. If Vz58 was a Harley, t81 is a moped.
It shoots fine, not very accurate, about 6MOA. Sights suck, QC is subpar. "Normal" bending of stamped receivers, which is just a sign of bad manufacturing process to me.
In normal country like Soviet Union bad AK stamping caused them to return to milled AK production until improvements in AKM model was introduced.
All that said, if people are buying them at 2.1K that's the current market price.
That's the thing, at the end of the day it's a POS Chicom gun with Chicom quality. Unless you feel there is some provenance due to the fact that slaves likely gave their lives in manufacturing them, they really aren't anything special.
For $500 I'd pick one up to play with and dump if I didn't like it. But for the "going" price, yeah, no.
