I'm very pleased with the end result. At first they might seem expensive at £13.50 (if bought alone) or about £30 for three on some discount sites. But when compared to mdf equivalents (which would lack the detail we have here) they are pretty good value for what in effect has produced two ruined buildings.
As stated earlier, my only real gripe is the degree of warping. I can put up with this though, it is a ruin after all!
