Hi Bob
I do not know where you are quoting prices from, I am going by prices and deals that I have found. 20s command higher dollars period, due to the ease of mobility, size constraints etc.
As far as contractors selling cheap yadda yadda, good luck.
I work for one of the largest electrical utility contractors in the world, and trust me, sea cans are gold on any job site and 99% of the time go from job to job. Contractors like us have things like float trailers, cranes etc so moving one is never a problem.
Our company has purchased several and they get used and used again.
I do happen to have a line on 3 or 4 cans (40ft highcubes) for around $2000 each plus moving from the Acton area.
Have you ever moved a 20 footer with your tractor? They are not as lightweight as you may think.
