The powders can be used with different guns as sparksandtabs said. Even though I use the Eastwoods gun (and also they're powders currently since I hold an account with them) there's no reason I couldn't use the others. I got the Eastwoods since in addition to the account I hold it was also on sale a year ago when I got it. If you keep an eye out you will find the Sears and Eastwoods powder coating systems on sale from time to time.
The steps and procedures I went through above are the same no matter what brand of gun or powder you're using. The steps are also the same whether you're powdering engine parts to a 289 small block Ford, like I showed above, or if you're powdering brackets or sprockets for your robot. I went through this since there was quite some interest in powders last year. A lot of people wondered what the process was and that's what I went through. Now that they've come out with these "hobbiest" gun versions for $100 - $150 they're with in reach and a good alternative to paints.
Here are some links to powder coating systems and powders from reputable places that may interest you. Each place does offer some unique colors the others don't. There are also other places out there besides these.
Caswells powder coating system
Caswell Plating's colors
Eastwoods Hot Coat system (this is the one I have)
Eastwoods colors (you have to click to the adjacent pages to see the rest)
Sears powder coater and colors
Becareful of a kiln, gas fired appliances are a no-no. The powder (or any powder for that matter) can be ignited. That is why they say an electric range or toaster oven to be used for curing purposes. I don't know if they have electric kilns, the few I've seen have been natural gas or propane fired.
Most powders when fully cured will resist temps to about 350 degrees. I saw Eastwoods now is offering a few colors (silvers and grays currently) good to 1000 degrees for use on exhaust manifolds.

Yes, I'd like to. It'd make our robot different from most of the others unless 500 teams run out now and buy a powder coating set up!

With the '68 Mustang I've been using the silvers, grays, and blacks for the engine compartment but there's no reason I couldn't do any of the other colors.
I can see it now, I'm going to out in the garage to 3 am the day before shipping because we changed the design and I need to redo the parts!
Now that would be FIRST dedication!
