I built one without any prior experience and it turned out great. I just read the pins method of gluing acrylic thread in the do it yourself section. I designed it on paper and then ordered the acrylic and solvent, and glued it up and it works great. Cost me about $80 and a few hours of reading and gluing. I was limited in room under my tank so I needed kind of a weird sized sump, I built it 24.5x10.5x14 outside dimensions and it fits perfect and leaves me with a little room for skimmers skimate storage tank and misc. stuff.
