i like to shop plumbingdirect.com - you can use the fixture filters to screen out categories and focus on just wall mounts and even narrow it for depth of projection.

Kohler is the #1 brand, I would check their website

Moen, in my DH's opinion used to be the best but we recently replaced our kitchen faucet and bought Moen. it was (is) plastic and the plummer said that Delta was the faucet he saw the fewest problems with.

thanks for all your input, Houzzers. I still haven't found a wall faucet with pull-out or pull-down spout (other than the commercial pre-rinse variety) so we'll likely go with the kind that has a separate sprayer.
Probably the sort we're seeking will go on the market as soon as we're done with the project! :) If I do find one, I'll post a link to it here.

Found one. The Toto TEL210GRV200. I have no idea whether it's good, only that Toto's warranties are reportedly very stingy.
