Its not very involved.
I bought a 20Lbs cylinder of CO2 from a brewery supply company, you can get them from most places. Welding gas companies will sell them, and they should be food safe, as its just gas.
I then purchased a regulator for beer kegs, this one, although there are cheaper ones. I like the dual-gauge ones because then you can see how much CO2 you have left. I keep it set to around 50psi, which seems to create the best bubbles.
I finally purchased a screw cap fitting that connects to a barb lock fit, which you can get from any vendor you like (MoreBeer sells a nice metal one). This screw-cap slots onto any standard US 2L soda bottle, and other sizes as well.

To actually make seltzer, or any other type of soda really, all you need is an empty soda bottle, and the above device. You put about a half-cup of water in the bottle, close it up, and freeze it.
When the water in it has frozen, bang the edge of the bottle on the edge of the sink or counter to dislodge the ice, and fill with water up to about the point the top starts to slope in. You want a bit of head-space.
Once its full, screw the screw-top I mentioned earlier half on, then squeeze the bottle to eliminate the head space. I like to squeeze to the point a bit of water comes out. Screw the screw-top down all the way, and ensure its firmly seated. The bottle should look a little crushed at this point. Shake the bottle a few times to ensure the water is chilled well by the ice inside. You need to have the water as cold to freezing as you can get it for proper carbonation to occur.
Take your gas tank, and open the line. No gas should be escaping, because the barb-lock fitting on the end isn't opened until the bottle is attached. Press it down firmly onto the screw-top of the bottle, and ensure it latches. The gas should begin to flow and inflate the bottle. The bottle should be quite hard. Give the bottle a very aggressive shaking for about 10-20 seconds. You may hear a noise from the regulator and note that the pressure seems to vary a bit. This is because you're dissolving CO2 into the water, carbonating it.
When you're done shaking, detach the barb-lock, and then turn off the gas. I like to turn off the gas after I disconnect it, so it blows any moisture out of the line as the barb-lock backs up. If you don't remember to turn off your gas, you may lose all your pressure as it leeches out around the seals in the barb-lock.
Now you've got soda. Carefully remove the screw-top fitting, being ready to screw it back down should the bottle start to overflow. I usually take it off and put the regular top back on. Keep it in your fridge, because warm soda goes flat almost instantly.

That being said, I've had such a system for a couple years now with no issues.
huh interesting!
I'd recommend something cheaper, that I do for small batches. Though different, it's very cheap, and effective. This is a soda pop carbonation cap
Get yourself a c02 tank from the brew store, it's expensive upfront but you don't have to bother buying expensive and wasteful little canisters. With this method you can keep it anywhere, you don't need to keep it in the fridge.
You basically force carbonate in the large plastic soda pop bottles. Shaking heavily for a few minutes. It carbonates very fast. Like 5 minutes. Just make sure the liquid is really cold. Pour that into your uKeg, or into some bottles for safe keeping.
