I like my Aeropress to be quite honest. It’s no more faff than a French press.

The ones you found are made of what to me are questionable plastics. I'd go for paper or natural materials ones. My vote is for the cowboy coffee. A last minute splash of cold settles the grounds down if you wish.DIY coffee bags.....you can buy permeable bags to make your own Tbags, they work fine with ground coffee too....and if sealed inside a mini zip bag, they last well too. If you buy good ones you can just burn the whole thing when you're done.
