I would have to assume that if you can justify the cost over a long term basis, kudos to you. It appeared to faciltate a particular need immediately. I just hope it doesn't get rusty in the yard.
Mazzochi/LVI seem to keep their high reaches busy.
I can still floor by floor quicker and trip more square feet in a day than any high reach. Red Mandell can prove the same doing floor by floor too! He's the best at it.
When you can demo about 32,000 sq.ft. a day of an eight story (heavy r/c)with your high reach call me. I'd enjoy doing the time study for you!
