If you like the key wells, definitely the Glove80. I have recently received my Glove80 (also coming from an Advantage2) and it is fantastic. They are available with Choc Red, Brown, White, and Pro Red, support tenting and use ZMK.
Glove 80 or Kinesis 360 would be my suggestion.
Something that’s a bit lighter, and less bulky. I would still prefer some tenting, or curve.
I can’t have my arms completely flat on the desk for longer stretches of time.
SliceMK has an ErgoDox variant that is wireless and low-profile using choc v1 switches. Disclaimer: I’ve been daily-driving one of their ErgoDox Wireless Lite keyboards for about 9 months. But I like the ErgoDox physical layout – been using one on a nearly daily basis for the past 9 years.
I’m a big fan of the LP Corne. The LP Kyria is also a good option IMO. Also the Glove80 has low profile keys and a curved keywell.
I really love the look of Glove 80. But, tax and shipping to Europe comes to a really expensive package. But, that’s more or less a perfect keeb.
The Glove80 Discord has a buy-sell channel, there are also regularly keyboards sold in Europe (which would let you skip tax). It’s also worth looking at local market places. Eg. this week I bought another good as new Glove80 from a Dutch marketplace for 150 Euro (admittedly, I got very lucky, but I do see good ergo keyboard deals every now and then).
Lucky you. I tried to ask what type of switches it had. But I never got any reply 😞
I eventually figured it out from the model type from one of the photos.
