The highlight of this set is the Commercial Grade Columbia Automatic Taper. You won't need a quick change cover plate to change cables twice a day. This Taper isn't a cheap toy. It's a big boy toy. Bar none the most widely preferred, smoothest running, highest production taper among the large drywall contracting companies.
When the market was hot a couple years ago, Columbia outsold it's closest competitor three to one, and it was more expensive.
