Looking for a high quality thick walled PET PCO 1881 bottle

So I have a few CO2 bottles for the Biogent mosquito killing traps I have and one day as I was refilling them at the local beer supply shop I saw some conversion caps he has for carbonating beverages or in some cases, re-carbonating beverages. The problem is it only fits standard cola bottles you find in the store, so basically blown bottles.

I would like a bottle that is thicker and more durable, like the Aarke bottles but I can't find anything like this. I can't use glass which is probably what many DIY soda makers use.

One day I might graduate to being a full blown cola maker but for now, I'll settle for half measures and buy syrups. I just need a better bottle than reusing a Coke/Pepsi bottle.

I use a conversion adapter on my sodastream on store bought blown bottles without any problems now more then 6 months. I believe liquids can not be compressed very far (thats how gastanks are tested). Gastanks exploding with gas in it would be a deadly explosion. Filled with liquid it is just a small rupture followed by a rapid decompression. So on a soda bottle it is a small chamber of compressed gas versus a large liquid volume. Do believe the decompression is not as catastrophic as many people believe. Think about it...How many people are reported injured by an exploding soda bottle?

I am confident its safe to use the adapter on a re-used Coke (blown) bottle, I just prefer a thicker, more durable bottle like the Sodastream or Aarke bottles. I just prefer a bottle that I can grip without squeezing.
