Lanemasters is a premium ball company. They're smaller and use higher quality materials. They don't get the advantages of bulk that, say, Brunswick or Ebonite gets. And they make their own stuff, no one pours for them.
As a result, their prices are higher than most. Their "mid-priced" equipment is in line with other companies' high end gear and their premium equipment is priced above everyone else's.
It's totally worth the money. That extra $20 gets you a ball made in the USA with high-quality materials. Nothing else hits quite like it and the longevity is virtually unmatched.
