I have a DIY window exhaust system (link to the post below). I turn it on when printing filaments other than PLA.
If money is no issue, I would go with an X1C combo. X1C has hardened steel nozzle and gears, which wear down less when printing filaments filled with fibers.
If you don’t have to buy it now, wait until the new printer comes out. It may have improvements that BL has learned from X1C.
