Home depot has their Flexilla copy air hose on sale for 14.88. I had just purchased this hose last week to blow out my sprinklers for 26.00. This hose feels exactly like the flexilla. It stays very flexible and is resistant to kinking.
This is still listed as 26.00 on Home depot's website, so this must be in store only. Edit: Home depot updated their website with this item. Looks like you can order online now.
