I am looking to purchase an undermount sink for our new countertop.

I was planning on getting a 16ga undermount from MRDirect, but they are now out of stock on the sink I wanted, and only have the 18ga. w/ shipping the price comes out to $188

The most economical 16ga I have been able to find in the same design is the Artisan which is $235, over $45 more.

I am wondering now will the 18ga be noticeably lower quality? If not, I would rather save the $45 and spend it on other items needed for our kitchen.

Any input is appreciated.
