Sports World, Central Mall (4th flr). If you don't see what you want in stock, ask to see their catalog, actually it's more of a binder with photos of pool tables, cues and available accessories. I believe prices are listed as well.
There's balls and then there's balls. If your getting equipment for an American table it's best to spend a little bit more and get Aramith balls. Your notice a difference if you play with cheap balls and then use Aramith balls.
I have a spare set of 'Aramith' balls if you can't find what you need ricks, they are used, but perfectly serviceable... PM me if you're interested (also have some spare cues... cheap).
