TBS it's a relatively new Chinese resin company
he released M-95 Degman, M-84, M-84A and a long family of type59 based line and a prototype Type 96A
T-72M4CZ is his newest addition with lots of PE details and corrected longer hull
in term of quality, frankly it's getting much better (I have the M-95 and type96A, the 1st one need many clean up and sanding and alignment and hole filling whereas the newer type96A is much more better in term of resin quality

)
PE details from his old series are a bit thick compares to big AM companies but very easy to work with
I haven't bought the T-72M4CZ yet but planning to do in near future but from what I heard from him the resin quality is even better than type96A
as where you can buy from him, personally I wanted to help him distribute in Canada but due to grad school i don't have much time as before, and he sells his creation on ebay =)
but be aware of that "3rd party" that is selling copied unfinished resin copy (he released a 1st version but I pointed out to him about the longer deck and he subsequently corrected it with tons of PE

)
hope these info helps you =)
