Currently S&W only produce the 610 revolver in 10mm. They dropped their autos, but they made a bunch of them, so they're pretty easy to find if you look around. They are all third gen autos and the model numbers start with 10xx (i.e. 1006, 1076, 1066, etc).
Colt used to make the 10mm Delta Elite. I have one and it's a great gun. They've become a cult gun as of late and prices are climbing well over the $600 mark.
There are other clone 1911 makers that still offer 10mm's.
Glock makes a 10mm line. Small and big size. Not much more needs to be said there. It's a Glock, so you pretty much know what you're getting. I personally don't like Glocks because to me they just don't feel right, but they are great guns and there's nothing wrong with them. If you like Glocks, then one of these would be the thing to get.
EAA makes the Witness in 10mm. It's a scaled up CZ-75 clone. I don't know much about how well they actually work.
Sig does not make a 10mm (I wish they did. I'd be ALL OVER that).
There are a bunch of other 10mm's, but the above ones are the ones you have a reasonable chance of finding, buying, shooting, etc.
For a general purpose 10mm auto, the Glock or a Smith and Wesson is the way to go. For a revolver, the 610's the only game in town.
