I have a Banish 223 and a Banish 30. Keep in mind that both Banish and TBAC put restrictions on your rate of fire, as these thin, lightweight baffles will NOT hold up to excess heat. You can fire a few closely spaced rounds through them, but then you have to let the can cool for a minute or two, depending on the air temperature that day. The full-auto rated cans are, of course, heavy.
Which brings up another reason I like the Banish -- if I do toast a rear baffle (or should I ever get a baffle strike from letting the can shoot loose) it is cheap and easy to get it replaced in the Banish. TBAC has to cut the Ultra apart to do any repair, and it is not cheap.
If you may ever want to shoot a larger bullet and don't want to have to buy two, get the 30-cal can. It does not attenuate the crack of the .22-cal bullet quite as well as the 223-cal can does, but it is very close. Either is wonderful compared to shooting unsuppressed.
If you get the Banish, immediately order one of the Chicago Rock Tumblers (often on eBay used for $60) and build one of the PVC pipe chambers shown in the video below. You can buy a 12" long piece of 4" PVC pipe on eBay cheap, then just handsaw it down to 9-3/8". Cut straightness is not critical because you are going to glue an end-cap there anyway.
The guy is doing brass in his modified Chicago but the system works great for baffles, too. Get a couple of pounds of SS pins (which are softer than the titanium alloy baffles) and some Dawn and you will be good to go, though I usually boil my dirty baffles in cheap vinegar (outside, not in the kitchen) for an hour to soften up the carbon before putting them in the tumbler. That cuts the tumble time way down.
Pour your wet, dirty pins into an old chamois shirt to strain off the water, then spread them on a cookie sheet to dry. You may want to set the tumbler on the cookie sheet when operating, too, to be sure you tightened the lid down adequately. Don't ask how I know that.
Banish recommends cleaning every 50 rounds, but that is, of course, not practical at times. Once you see how much carbon builds up in the can after 500 rounds you will be glad you got a can you can easily clean yourself.
Good luck and enjoy!
