Welcome to the forum!
For quality leather gear, my go-to sites are Mr. S Leather (
https://www.mr-s-leather.com, located in San Francisco) and Sinvention (
https://www.churchofsinvention.com, located in Ontario, Canada).
There's really nothing from either store that I can't recommend...they're both extremely high quality (a fact reflected in the price). Also a big fan of both vendors as you can often ask for a level of customization in their gear as well (e.g. adding locking buckles, custom sizing, etc.). The leather hoods and cuffs I've got from Mr. S are the most comfortable (and secure!) that I've ever had (Fetters Padded Locking Wrist/Ankle Restraints, Deluxe Tight Hood, Isolation Hood).
To further echo the previous comments about gear from JT''s Stockroom...I have a VERY comfortable set of padded cuffs from there as well (Premium Lockable Dungeon Wrist/Ankle Cuffs), and while (to me) they don't feel as heavy duty as my Mr. S cuffs, they are perfect for a tight spread eagle due to all the padding.
Concerning Autumn's Sub-Shop, that was the first place I ever ordered bondage gear from...and that was about 15 years ago! Was able to get tons of gear for a couple hundred dollars...and while it was a great introduction to "real" leather gear (and perfect for my budget at the time), there's absolutely no comparison between that shop and the others mentioned.
Happy hunting!
