I was given one by a guy that I bought my cooler mash tun from. I suppose it depends on what you're expecting from it. I've only used it to take beer from my kegs to a homebrew club meeting. I'm not too sure about using it for any kind of long term storage though. I used it tonight to take some for some co-workers to try tomorrow. I'll see how that turns out after letting it sit overnight with it on.
I have several carbonator caps and use them all the time. You can force carbonate your beer or other beverages easily and quickly no problem. They are a little pricey, but they last indefinitely.
FIY, you can make your own carbonator caps if you don't want to pay the rather high price for the manufactured type. It's basically a tire valve through the bottle cap. Try a search on this board and you will find the DIY info for them.
I don't know where you can get them for less, but it might be worth checking all the online sources.
Have one, use it to carbonate almost anything- no complaints (just watch the poppet when you unhook it, tends to seat funny on occasion and needs wiggled to hold pressure).
FYI I will carb water with it at like 40 PSI and it holds up like any two liter of store bought soda. I haven't let beer go that long in one, but imagine it would hold up better then a growler, since you can recarb it and help against oxidation more (just watch the light factor).
I was looking into making my own, I have pretty much everything I need at home except for the tire stem so I think I'll give it a shot. I'll reply back with the results.
You only need one Carbonator. I chill the beer, put the Carbonator on and force carbonate, then put the regular cap back on.

Mine leaks sometimes. I lost a whole CO2 tank because of it.
I never leave the gas hooked up to my kegs or to the carbonator cap for just that reason. The exception would be for a party or something where I am serving more or less cotinuously. Even a very tiny leak in a keg or the carbonator cap would empty a CO2 tank in short order. Been there. The carbonator caps are not much different than a gas in post on a keg. There's a poppet and an external O-ring. I've replace the o-ring, but not the poppet. Not sure how to remove the poppet or if it is even possible.
