Hi Tom,
A sharp bottom bedknife blade and a sharp reel, carefully adjusted, are essential for a good cut....backlapping will not achieve that...and can result in more metal having to be removed in a spin grind, due to a wavy reel and bedknife. wink
As for the where and the price, just ask your local greenkeeper at the closest Bowling Club, where they get theirs done. wink
cheers
