Well I think they would hold their value for the most part. I mean Meng acquired the Dr 1 molds and managed to take things down a notch, and maybe Border did a great job. Just depends I guess.
No they sold upgrades seperately on purpose. Apparantly the cockpit oob has some issues, and this is tge first from a seperate company. I just have an addiction to a m cockpits.
Has been released by Resin2Detail. It says future release on here, but he announced they were ready on FB last night
