Anyone use Versatube? Would like opinions for garage build.

As I continue to struggle with my garage aspiration (contractors, County nonsense, and materials issues), I am looking at VersaTube so I can assemble the building myself. I am looking at a 34 x 34 x 12 building. Using their building planner on the website, I've made 2 styles: frame only and one with metal sides/ roof. I've sent an email to VersaTube to ask if I can use a shingle style with plywood roof and what materials can be used for sides. The price for complete with 3 9' x 8' garage door openings and 1 entry door opening (no doors supplied in kit) is just under 19K (I upped wind load to 120mph). Frame only is about half the price, about 9.5k. I didn't select insulation either as I think I can either use spray foam or foam board. (cost to insulate is 3.1k with Versatube).

Does anyone have a VersaTube garage and do you recommend or not recommend?
What problems have you encountered?
Did you use your own materials for sides/roof?
Is it worth the savings to get the frame only and finish the roof/sides on my own (so I can match the house better)?

It is "possible" for me to try to make it out of wood, but it would be a lot harder to get it started. Pre-engineered metal is easier for me and termites don't eat metal.

Thanks for the advice.
My wife and I put up a Versatube carport that was 12'x18' to cover our pontoon boat. The framing part was pretty easy. The frame pieces just slide together and are fastened with sheet metal screws. The cost about two years ago was $1200 for that size. I like the system real well and would do it again in a heartbeat.

Your project is much bigger than mine but the building principle is the same. If you use regular building materials to cover it it's going to get pretty expensive. The sheeting that comes with the kit is regular pole barn siding material.
I put up a pole barn also and that was about $6000, 8 years ago. 26'x32'.
The Versatube kit was way easier.
