Nope, just buy one, you won’t be disappointed.
I brought just the frame and wheels from Alpkit and built the rest up myself. Spec is: 140mm Reba’s, SRAM NX groupset, WTB Rangers, 3” front 14psi and 2.8 rear at 11-12 psi, Brand X internal dropper, 40mm stem with 780 risers and deore brakes.
i can’t tell you how much fun this bike is, climbs like a mountain goat, flies down hill far faster than is healthy and never fails to put a smile on your face. It’s light, agile but confidence inspiring and planted. The semi skimmed tyres give enough squish and contact to really push and take the rewards. Everyone who has ridden mine has had the same reaction. Fun, really great fun! In fact 2 riding buddies have now gone and brought frames to do their own Transmitter builds.
The carbon version, although made from the holy mystical substance, doesn’t save you that much weight, so I’d save some coin and by some toys / upgrades
I’ve ridden everything on mine from local trails to the Peaks (potato alley and Jacobs Ladder) to Cannock and Chicksands and there was nothing I threw at her that she didn’t cope with brilliantly.
Look at where the Transmitter family tree comes from (Ragley), is it any surprise with that pedigree, Alpkit made a fantastic, do it all, one stop shop, hooligan of a bike.
Ride and enjoy.
