Fully agree, however the OP stated he didn't have time to build one and money wasn't any issue so therefore is exactly what he asked for lol.Last u remember their sumps start at 1500. I thought about gettinv one too untill i took the time to learn about sumps and other members pointed out the flaws or waste in their sumps.
Imo its nothing special more like a waste and probably the same amount of work in setting up his 75 as a sump
