[DISCUSSION] Best place for Gundam models?

So I've been getting back into Gundam models lately after at least 7-8 years away from them. I started out modest with a 1/144 scale HGUC Nemo from Gundam Unicorn to test my skills, then moved onto a MG Gundam X that I just finished up tonight. I'm looking down the line to pick up more kits, especially MG and a few specific SD kits, so I'm trying to figure out the best sites to order from. Amazon seems to have decent prices sometimes, but some seem to come from sellers I've never heard of, and some have crazy shipping prices because the sellers seem to be based in Japan itself.



Any good ideas?
