If it's not kangaroo and there isn't a perforated version available $ 1800 is way too much!
Consider Berik
::BERIK RACING DEP.:: or M-Tech
MTECH - Track suit .
I am currently considering an M-Tech because my trusty old Dainese has become way too large for me and having it reworked would cost me about the same as a new suit. Pricing is much, much lower than RS-Taichi though neither offers kangaroo as an option.
If you have problems finding them drop me a PM and I'll see what I can do.
