Online. I bought on impulse at the LFS and paid 25% more than online.

Why not just fix the leaks?

Where is it leaking at?

$18.50 is well worth it IMO to have the peace of mind that it won't leak, or at least is a lot less likely to leak.

Rex has a good point. The hagen bottles are much smaller...in my case I ended up adding an additional bottle to get the rate of co2 I was looking for. Generally, the diy co2 bottles are larger...

I made several diy, flat bottomed, juice bottle co2 unit a couple years ago. All it took was to drill a hole smaller than the small plastic airline connector, spread some epoxy around the rim of the hole, force the airline connector in, let it dry. Spread some flexible adhesive (Marine Goop) on each side of the lid around the airline connector, and voila! And if the lid is leaking around the mouth of the bottle, you can simply add some plumber's tape. I'd give the diy bottles a second chance.

Easier than that. Use a drill bit smaller than the OD of the tubing. Drill the hole. Cut the tubing at an angle and pull though with pliers.
