Scott, are you sitting down? I paid $13.80 per foot plus taxes picked up for the Logstor (3 hour round trip) Local guy wanted $10.00 ( - 20% discount) for the 3 wrap. He wanted $15.00 for the logstor or at least it looked like logstor, with 2 week delivery. The 3 wrap was definitely field tile and was what he normally used. I dug and filled the lines myself so I did more than would normally be done. It was all clay so I hauled it away and used gravel from my gravel pit to go below the tile and to cover it. I sloped the grade so water wouldn't be an issue. I also did a small run using electrical conduit and going to put homemade lines in it, separate run so no biggie if it fails. I'm planning on 1' pex inside of grey foam that is used for water lines. Local electrical supply can get it for $1 for 6' piece, conduit was $1.45 a foot. I'm going to put sensors on it to see what the heat loss is. I need a 100' run to my shop and because it'll run inside a heated building I don't need logstor for it but want it insulated.
