I'm not positive.  I think it was Insight plus Tru Count, and the planter in question was actually a narrow row, so there were 36 instead of 24.  Wouldn't make any difference with my system, but it makes the tru-count a lot more expensive.

The Insight is about three times as much as the EZ Boom.  Myabe it's that much better, but the EZ works just fine.  At the time I did ours, EZ on a planter was unsupported so mine is a roll-your-own application.  It went flawlessly, though. 

The tru-count clutches were somewhere north of $300 per row, and then you had to buy all the air compressor and solenoid valves and associated stuff.....and you were buying for 36 rows even if you were only going to control them three at a time....not to mention all that unecessary compexity to keep working.
