Grintech has some, but it just says JST but he's also got the crimper if you need that, or go generic.

For the Aliexpresses of the world, if you choose E-Packet for a shipping option, it comes way quicker but the E-Packet is limited in size and weight, not an issue for you and your handful of JST's.
The 3 times I used it at Fastech, Hobbyking and another place, within about a week it was delivered. Last one was from Hobbyking from their Hong Kong warehouse, ordered about 5 months ago, came in about 8 days. That box was 1/4 the size of every dimension of your bog standard shoe box, 10-12 pairs of XT90's.
Fastech should have those JST's
DX is another option.
