sump pump basin

Does anyone have a source for a sump pump basin that has a sealable, two piece lid that has a floor drain incorporated in it? Basement Systems has the perfect one called the Super Sump, and I'm coming up empty trying to find a similar product. I spoke to their rep about buying just the pump and basin, but they are not willing to sell just that; they want to do a complete drainage job. (Hmm, that NEVER happens in our trade :)) My site conditions are so challenging-ledge, stone foundation, boiler and well tank are suspended off the floor joists via unistrut (for this job), etc.,etc., that I want to tough it out myself to get it right.

Couple weeks ago I jackhammered up my basement floor to find a suitable spot to sink a sump/lower floor/ get stone under the slab/install vapor barrier/repour floor. Major ledge. Last weekend was spent with a 4" diamond grinder and my Hilti chewing out a deep enough hole (24") to accept most sump basins. It took 4 hours to gain 1.5" depth in a 16" diameter spot, pumping out water as it came in, Grr.

TIA!
