Somewhat more recommended than other places to get juggling props:
http://thebagladyonline.net/
-Flannybags: custom sizes and weights. Have seen and tried sets from this store - one said they had /aquired/ them, in a solemn voice. This store has been around for a very long time. Notable thing: if a 130g ball is too small in diameter, but also too heavy, they have a solution for that without just underfilling the balls.

-Oddballz, at a new store location now, previously in Camden. They run a good selection of Juggle Dream thuds and balls in different sizes - Juggle Dream have thuds with slightly bigger diameter, at slightly lower weight, compared to the Babache beanbags. Well made in all price ranges, the difference is in the material.
Oddballz generally add descriptions that are actually useful to jugglers on their site, but they also respond very thoroughly to questions (and will recommend against something that won't suit you, even if you ask for expensive silx and mx balls, for example). They also have the modernized version of my "uglies" set, in either 90g or 110g.

Only carry the popular things that sell, but if you were looking for something specific that they have, they have free shipping on orders over £40.

Mr. Babache. Expensive, but excellent. Is it worth it? I have several sets from them that I love, but never use.

Also comically expensive, but unique with the high number panel thuds. The (good?) idea with filling the outer layer of a thud with a heavier material(sand, rubber grain), and the center with a lighter plastic millet, comes from here. It's basically a thud that flies a bit like a russian ball.

Does this work? Possibly, yes. It's a good idea for trying out different weights that I would never have thought of.

Norwegian, Norwegian sand, extremely awesome, recommended by Hvidsten and Dragsjø. And extremely specialized for low-filled russian ball feel, in large and small sizes. Tried them, admire them, and never use them.
In the end, though: a juggling ball really doesn't need to be extraordinary or expensive. It just needs to be good enough. Because there really isn't a way to make a beanbag more than just a beanbag.
