5" flex hose What manuf. seems to be the best deal?

[juicegoose]

currently I've only got some 4" flex hose for my 50-760. I'd like to pick up about 25' of the 5" flex hose. Several manufactures carry it but all of them use different specs to describe their product. Of those of you who have bought 5" flex hose where did you get it from and how happy are you with the performance. Has the hose held up well? Does the hose seem to have a relatively smooth interior surface. All that jazz!!

Thanks guys.

Also my two front runners right now are penn state and wynn
They both have about the same pricing on their 25'-5" sections of flex hose.

Just noticed no one replied to you.  Grizzly has inexpensive 5" corrugated HDPE flexible pipe.  I believe the 10' section I purchased was less than $20.00 or so two years ago.  I just needed a small section to connect from the Delta 50-760 to the container so quality was not a big deal.
