The adidas are quite good according to some of our members. I personally havent tried them yet so I cant give them my stamp of approval just yet.
I still like Ringsides IMF Tech glove and you can get it in higher weights. Only problem is, like you said, getting them outside North America for reasonable shipping. Doesnt hurt to check though I suppose...
