Lance, I paid $25 for 2 complete WAG units on a farm auction; I guess I have the best set up of all?

They are talking apples, you are talking oranges.

Your talk of needing to "nudge" on pass-to-pass tells me volumes about how straight your system really sets out the rows.  I'm glad you are happy (as you should be), I'm sure I'd be happy (since I often cannot see the end of my planter, grain drill, because of dust.)  Not everyone's needs are the same; some people want straight looking rows, some people want repeatability for future operations.  I'm glad you got the opportunity to explain your system.

When the new free signal becomes available maybe some used equipment will become available to make it cheaper to get into a good unit.  But, just because the signal is free makes no guarantee that the equipment will be affordable.
