I pretty much agree.
I bought Sue a Boss pedal board, only a small one, when she first got a few pedals. It was £90 with a power supply and cables & fittings. In pedal board terms it was a good price I think as it was well designed and flexible. However, £90 for a bit of molded plastic with some foam inside and a power supply seems like a lot in anything other than pedal board terms!
If you can make your own, I'd say do it, unless you gig a lot then you might want to buy a hardcore flight case type deal to protect your gear.
