Yep, I figure if I can buy a section for 40 bucks or less I am ahead and they will not depreciate...
I usually find the 10ft x 10ft x 6ft tall for $100($25 per section)--If it has a little repair needed I pay less and I repair it back to Factory look---no junk looking repair---even if a pipe is rusted/bent/etc I replace it. Did I mention how EASY they are to install--LOL(for the ones that do not know). At 60--I did this section/run in one day---by myself. 10ft x 150ft long divided into 15 breeder pens(I got lucky and found some double doors in several 10ft pieces). I did the netting over the top the next day. Easy!!
