I used a variety -- rev-a-shelf, another brand from Target, Ikea. And, I wish I could remember the website, (but I found it by googling) that offers all kinds of wood interior, aftermarket fittings, drawers and shelves. Oh, there is Lee Valley, too!

The Presenza from Costco is the better choice because it is made of thicker steel. The thinner 20 ga. steel is too thin for sinks, and you will not be happy with it. A 16 ga. sink is even better. The Presenza sink is made in China as is the Glacier Bay sink. A better choice for you may be an asymmetrical sink with a small bowl paired with a larger. The small bowl is handy for food prep, and the disposer should be placed in this bowl to dispose of scraps. This one is from Franke, but almost all stainless manufacturers have one or two. Most sink accessories can be purchased separately. A cutting board designed to fit over the sink, is a common item at Amazon. A strainer can just sit in the bottom of the sink. It does not have to slide along the edge. But if you want one that hangs on the edge, try something like this, from Amazon: One accessory that is useful and usually must be obtained from the manufacturer is the grid, which prevents a lot of scratches on the sink bottom. Be careful of zero-radius sinks. Those sharp corners are hard to clean.

Yes, I bring home about $30/hr in my line of work, and I am at the top of the pay scale! Show me a tradesman, any tradesman, that values his time that cheaply. If I choose to cut down and install a drawer or install my aftermarket trash pullouts on my own dime and time, it has given me pleasure and has been cost-effective. I would never sign a contract that includes certain feature or accessories then renege because I found another source. I simply didn't include those options in the contract in the first place. I did do my homework to discover what certain things cost in the aftermarket before contracting the cabinets. Some things I added later because at the time of the remodel I was at my limit of available $$. I feel that I have a duty to manage my resources carefully. The OP never suggested that he was going to sign a contract then "micromanage" the cost of the accessories.

Elkay, when I remodeled my kitchen in 2012, the KD suggested the pullout cutting board on glides over the trash bin, similar to the one shown in the 2nd photo in your original post, i.e., no hole in the board. One difference was that drawer front pulled down, rather than being attached to the cutting board. I thought it was a great idea and went ahead with it; however, it was not useful. When I remodeled again in 2015 (long story), I took out the cutting board and replaced it with a horizontal spice drawer. Also removed a narrow pullout spice cabinet that had been installed next to the range in 2012. Problems with the pullout cutting board were: (1) It tended to move around when I was cutting. I prefer to have a work surface that is immobile when I have a sharp object in my hand. (2) Juice from cut fruit (tomatoes, oranges) rolled off the edge of the board onto the floor. (3) When the cutting board and trash can were extended, they blocked access to adjacent cabinets and counter space, so I needed to make sure I had everything ready before I started cutting. (The board was near a corner.) I compost fruit and vegetable scraps, so they go into a compost can on my counter, not into the trash can below, so it was not that useful. It took up valuable space that was better served with a spice drawer - I didn't like the vertical spice drawer because it meant kneeling down to reach the spices on the bottom shelf.
