[TowerTalk] 4 squares - Comtek Phasing Box - how is it's accuracy ?

I thought I posted this yesterday but think I put the wrong address in.

Is the Comtek box the best way to go for 4 squares?  I like to experiment,
but from what I have read, I need good equipment to accurately measure
antenna impedances.  What do people typically get for gain in a 4 square
using the Comtek box?    Can I expect to get away with elevating 40m
verticals and still get good performance?
