How much less complex would the round 2 beamsprings be to set up? also does the iso option come with uk keycaps?
Yes most likely; no rush.
Same steps for each model. Things get bounced around in shipping, regardless of model, so you have to fix them when the shipment is delivered.
There is only one key set layout available, offered in two color schemes. There is no separate set for ANSI and ISO. The only difference is the colors. The key set has a combination of keys to allow for ISO and ANSI layouts, but it does not perfectly cover all possible layouts. I posted photos of the layout on the product pages so you can look at every key in the photo to see what is included (except for the pictured ISO enter key with the conditions described below).
Due to the ISO key cavity being in the mold containing the non-modifier keys, the keycap is white with black text if you order the key set that has white non-modifier keys. In this instance the ISO Enter key is included at no extra cost. If you ordered either key set option and require a black ISO Enter key with white text, it is an extra fee as the factory could not manufacture extras of any key and I have to remove these keys to save for those who need ISO Layout with either key set color scheme.
Yes, feel free to use a third party set. While it should work, as noted on each product page no guarantees are available and it is disclosed that you may damage something, just because I have not tried every MX set for compatibility. While the sets are ANSI and ISO they are not region-based, so they would not be specific for Germany, the UK, etc.
Neither option is complex to set up. Feel free to take a look at the beam spring setup video for details. Yes there is an ISO enter key available. Please see the photos on the project pages to see each key. There is an extra charge for the ISO enter key S per the beam spring product pages.
ok but how much less steps would there be to set the round 2 keyboard up as opposed to the round 1 boards?
Also wouldn’t the iso enter just be included in the key set? if its not then I’m guessing the key set is just the ansi layout even though I picked the b104 keyboard with iso layout option? Im just a little confused here.
Maybe it might be easier if i just get it without keycaps and get a third party set when it arrives.

Ok thanks for awnsering my questions. one more thing. I didnt get paid as much as I thought I would this month so I might not be able to buy this until later this month. will the sale still be going on until then?
