Bowlingballdiscount.com normally has some international releases, however, there are some websites in the UK that sell all the rotogrip international releases. They are really expensive after the conversion and shipping cost. For example, I wanted an Alliance and it would have cost me $213 for the ball alone, with no shipping cost added.
My opinion is, if you have deep pockets or the ball just really matches your game then have at it. But, most international releases are just cover adjusted models of the US releases. For example, the alliance I wanted was the precursor to the Cell Pearl. Same type of reaction, Very subtle differences. Just something to think about.
