Hi JoeG. I know what you mean by "cheap", frugal,thrifty, etc. cause I'm the same way. The floats (4)48"x72"x12" & (1)36"x48"x16" cost $997.00 + shipping. The stainless steel screws were $100.00. The rest of the hardware(incld brackets to secure gangway to pier & roller brackets for gangway to rest on deck) costs $1798.00 + shipping..I seriously considered the Canadian style floating dock with styrofoam, but that was done prior to new pressure treating formulation and it kind of spooked me off any non-stainless or heavy galvanized hardware system..good luck on your plans..du
