Honestly id buy it for twenty bucks. Paint it or cover it in stickers, whatever your style. Drill holes as you need, screw in handles.
For those of us without decent tools and who don't need something as... pretty as a pedaltrain, why not?
I think its cool that there's something filling that price point for sale, why not?
Beats being the guy that has to sell a pedaltrain when he changes pedal numbers or gets tired of stompboxes.
That being said I'm frivolous with money. Fifteen bucks and id call it solid.
Plastic is crappy and metal is expensive, and if its metal and cheap , Itd be harder to modify
