I don't want to hijack this thread, but I do build a lot of sumps. What I try to get people to understand is that I cant build them as cheaply as the 'big boys'. They buy acrylic by the train-car where I buy one or two sheets. I don't even try to compete with internet pricing. What I do is custom. If you have some special needs, size limitations, or just want exactly what you want, that's when I can help.
