I have the Diamond Super Single and I love it. I originally ordered the Cascade but the backorder kept getting extended so I went with the Super Single. If you wash a lot of big items it is awesome. My pancake griddle fits in it with room to spare as does my largest pot and sasucepan. I also use the blanco sink grid which lowers the depth a bit.

As far as the Precis fitting, check your interior cabinet dimensions to make sure you can fit the lip in if you are undermounting it. It's gonna be close!

I have the cascade and I have had no trouble fitting anything in it that I've needed to. I used to have a deeper double stainless steel and I find this to be an overall improvement and the width and depth has not been an issue and I have washed some giant soup pots and Dutch ovens in there. The raised part comes with a metal basket and I keep stuff in it like the drain stopper and a washed travel mug, just whatever you want can go in there.

I have the precis cascade - 33" sink base so no choice in my mind as it wasn't recommended so I didn't dare try it. There has been some debate both ways on whether you can 'make it work' but I preferred to err on the side of caution (read - new construction I did not need any more issues at the 11th hour). If I could have chosen I think I might have gotten the super single because it was more economical. I don't miss a double sink at all and I don't think I have ever heard anyone complain that their super single was just too big. :D

Precis specifically:
The raised area I do like and I use it. I can prop items there against the lip to dry. I use the basket for silverware or small items sometimes. If the dishwasher is full and running and I have a few things I like that I can put them there and they are essentially not in the sink? That way if I am fussing yet they aren't in my way. I like that I can have those few things waiting and still have my sink 'clear'.

As far as size:
9x13 - no problem. Stock pot - no problem. Cookie sheet - not flat but only at a slight angle and I don't normally soak mine immersed so again no problem.

Blanco specifically: I love this sink. It's quiet. It cleans like a breeze (and we have well water). It hasn't scratched at all. It sort of blends in aesthetically yet stands out because it is so awesome.

Thanks, everyone! I knew I wanted a single bowl instead of my current double one (I've had both and I don't find a single advantage in the double - it was here when we bought the house), but of course it's always nice to hear about agreement on that! It's sounding as if I should probably do the Cascade, since I also don't want any little glitches and it sounds as if it holds big enough things for me - although I guess I'll go measure my roasting pan just to be positive!

I love the super single! As long as all of your things fit in the cascade, it will have the same advantages, though. I just love being able to hide an entire dw load of dishes in the sink while I am waiting for the dw to be finished/emptied. You will love the silgranit!
