Thanks a lot for the comment! I did not reply sooner because I have been throughly looking at the products you suggested. These are very impressive! The zoom65 looks much refined than an entry level keyboard, at least, their advertisement is very nice and it explains some features that for me at least are kind of "premium".
For the shake of other readers, I will only point out that the zoom65 does not have any kind of LED lights.
When comparing both, the Keychron Q2 and the Zoom 65, the main difference is the bluetooth and, in the case of the Zoom65, you get an aluminum piece to improve the sound and the weight of the keyboard. However, you lose the LED lights that the Q2 has. Furthermore, in terms of money, both are nearly the same. The Q2 is about 159$ in its barebones ISO knob version and the zoom65 in European dealers is 179€ (179$ in the international dealers). Shipping not included that is free for the European dealer.
To this, you need to add the switches and the keycaps (if you have ANSI, you get these just for extra 20$), which I would say there may be another 100$ / 100€. Of course an entry level PBT keycaps without any fancy staff in it.
As a summary, it is a pity that for an affordable ISO layout keyboard you have to spend such amount, definitely you are getting a much higher quality than a 40€ amazon ANSI mechanical keyboard, but even though these are all plastic, you can get your hands into a mechanical keyboard to start with, and maybe try some switches.
I will probably get the zoom65, but is weird that there are no more options. I mean, in Europe ISO is the standard, I can deal with the keycaps, that these are country specific, but regarding the layout, it shouldn't be that difficult to produce both alternatives... I have also looked for ISO PCBs, but these are not worth the money, maybe 60€ for just the PCB, adding housing and the rest of parts easily passes the zoom65 or Q2 price.
Thanks a lot for your comments!
