I have to say those Brett Sherwood cups look amazing in that link.
I wouldn't really recommend the alluminium ones, I brought a set of alluminium cups and balls with a chop cup included, and I've only practiced with a it a bit, and there are already dents and scratches on them already.
I'm not mistreating them or anything.
And just looking at that link just, mine has all the "qualities" of the poorly made cups...
If only I saw that link earlier.
I got mine from MagicBox, not sure what brand they are though.
