I would just wait. The TDKR Armory version is already obsolete. This one has a better armory, more accessories, a better Bale, etc. etc.
BUT
We know they’re going to release ANOTHER TDK/TDKR DX version. That one will have the faceplates that are missing on this these past two along with an updated Sonar head and cape back pack. Probably be released as soon as InArt puts up there’s. Someone in the other thread said it best, Hot Toys are drip feeding with these releases.
It’s an endless cycle. The only people that really win are collectors like you that haven’t bought any of them yet. Why? Because after these TDKR armory and TDK armory figures hit the market, you’ll have roughly 8 Hot Toys Bale Batman figures to choose from on the secondary market. The prices on suits, belts, gadgets, heads will just get lower and lower. That’s not even counting InArt’s eventual release.
Hot Toys have really diluted their brands. The DX19 took forever to sell out and every store still has the QS019 (both versions) for sale.
