099b. Which OpenBCI product would be currently most interesting for users?

If we look at the following information:

096. Positive & negative experiences with products based on the ADS1299 EEG chip from Texas Instruments

097. Farmer’s cleverness (part I): How YouTube video makers got rid of products which where annoying to them in the examples of the Dreem 2 headband & PiEEG?

098. Farmer’s cleverness (part II): Sell cheap inferior OpenBCI products to smart people as long as you can?

099. Known issues of OpenBCI products which are not sold by www.OpenBCI.com

Then you can see that there are a lot of products with a lot of issues. If there would remain only one without any issues which is sold for a good price, OpenBCI would be interesting again for Swiss users as well. And that one product is

PiEEG sold on Aliexpress for 230 USD

This would be one simple product sold for a good price with low shipping costs also for Swiss costumers. And are all the other options not outdated concepts. Outdated concepts for Swiss costumers like us?
