[TowerTalk] New to Group, WTB M2 OR2800PX and Rohn TB4 Thrust

[Patrick Greenlee]

Many of us go bargain shopping and install marginal equipment. Those 
choosing professionally re-purposed prop pitch motors such as those 
provided by Kurt Andress complain less as they have little opportunity 
to do so. Installations of equipment on your (below mentioned) list are 
not the majority topics for a couple reasons: 1.  They don't fail as 
often and 2. They constitute a small minority of installations.

The above is my personal opinion.  YMMV
