If you have a 36" cabinet base I think you have a lot of options....look online at efaucts, faucetsdirect, qualitybath etc..

If you have a 30" inch base (like me) you have fewer options. I just use a colander in the sink to wash/drain veggies/fruits. I have a clear plastic liner tray(the kind a dish drainer sits on) sitting on the counter next to the sink. It's not super noticeable and for us this is a small corner so it is dead space anyway.

I have a single Kohler Whitehaven apron front sink and love it. I have the stainless steel protector rack so I no longer need a counter top sink drainer as I can allow my dishes to drain right on the in sink rack. I really dug in my heels about going from a double to a single but DD finally convinced me. I am so glad I listened to her! It is the most versatile sink I can imagine.

I have a 36 in sink base with a 60/40 double bowl SS undermount sink and I love it. I measured the sink bowls to find one that would fit a small dish drain but I find that the flat rack in the bottom is sufficient and I have never bothered with a drainer. I love the clean look of the counter with no dish drain on it and I like having the smaller sink to dry dishes or rinse something or wash dishes in during holidays. I ended up with the Kraus KBU24 and am very happy with the quality.
