KGH is indeed more reliable. I think their current price is about $940.No. They’re not an official dealer. If you preorder through them you’re going to wait until they can source one. They’ve also have scammed people who they couldn’t source for by delaying them past credit card protections, and have occasionally shut down their contact email.
KGH Hobby has them in stock as well and are much more reliable but you will pay a bit more. Also not a preorder actual stock
