Simple answer: Yes...
I have both one of the Bowie bottler setups and a Blichmann Beer Gun... I use the Beer Gun far more due to how easier it is to use, setup, and how you can fill as many bottles as you wish without touching the faucet. One piece of advise I'd give on the Beer Gun is don't get the accessory kit, just get the hardware to connect the CO2 to it via a ball lock post (or pin lock if that's the kind of kegs you have). I did it and it's far easier to setup/tear-down that way. Plus, you can use a standard gas line setup (I have several 'spare' lines and CO2 bottles/tankes and regulators). Follow the included instructions and you're good to go.
My largest complaint with the Bowie setup is the o-rings in the fitting. I know there are two different sized o-rings, but I cannot tell the difference between them on the fitting, nor in the spares that I ordered with it. Plus, you get the wand and tubing setup and you have to do more to get that 100% working. Not to mention, that if you use the pre-made add-on kit, it's easy to get beer shooting up from the bottles. Not so with the Beer Gun.
As I said, I have, and have used both. No matter which one you get, be sure to chill your bottles down to the brew's temperature before you go to fill them up. I'd also carbonate a bit higher than you would normally to serve from the faucet, so that it's less issue IF you lose any carbonation as you bottle from keg. Experiment on your own and decide.
