>>7304908>NECAHonestly, BBTS is pretty much your best bet as far as I'm aware of. What you might wanna look into is either stockpiling different figures over a few weeks or months with their pile of loot system or get yourself a US mail forwarding address like Stackry if you're on places like Amazon and Ebay looking for older releases, NECA or anything else for cheaper.
>FiguartsThis one also depends.
Most cases for regular new stuff, you can use sites like AmiAmi, HLJ, HobbySearch or Nippon Yasan.
For stuff like Bandai Exclusives like some of the Dragon Ball stuff for example, usually a site like BBTS or any others you can research into are a safe bet. I'm pretty sure Nippon Yasan also carries exclusives from time to time as well, so there's also an option.
For everything else, new or old, Mandarake. If it's something Japanese related, searching under the Japanese name usually brings the best results, so have google handy. Alternatively, searching Yahoo Japan Auctions can also bring up some surprising stuff depending on what you're looking for. You'll need a proxy service for YAJ, so something like Zenmarket is what I'd recommend.
