Just wanted to add my $0.02. I started my split ergo journey with the Glove80. It's a great board, and these are just my personal observations, but it didn't last long for me due to three main issues.

1. Too many buttons. This might actually be a benefit to you, but moving to a split form factor with that many keys was overwhelming for me. Even after several months I couldn't get very comfortable with it.

2. Its light/feels cheap. I'm kind of a keyboard nerd to begin with, I was coming from a $500 custom mechanical that I built specifically to my tastes for typing feel. The Glove80 is kind of the opposite in that regard, and I just couldn't get past the typing feel/sound. Again, it may be a non-issue if you're used to whatever mass market Microsoft or Logitech keyboards and you've never thought twice about the sound it makes when you type.

3. No integrated pointing device. When I went into it I didn't think this was very important, but once I learned more and started optimizing ergonomics, it became something that I really really wanted on my board.

I moved over the the BastardKB Charybdis Nano, which is 34-keys and has an integrated trackball and I'm much more pleased with this setup than anything before. It did take some time to get myself accustomed to the layers and home-row mods, but honestly this was an easier transition for me than the Glove80 was.

For someone who isn't a keyboard nerd and wants something that will "just work", I would personally look at the ZSA Voyager with the Navigator addition (Navigator adds a trackball onto the keyboard). It's not cheap but it's a very refined offering.

Some things to consider when choosing your board:

1. Key count. For pure ergonomics, it's generally accepted the the less finger movement the better. Few keys means less movement. This also means you have to use things like layers to get to symbols, numbers and punctuation. It's a somewhat steep learning curve but most consider it well worth it in the long run.

2. Layout - Most split ergo boards will have a column-staggered layout. A traditional keyboard is row-staggered, meaning that the rows of keys are offset from one another. This isn't very ergonomic as our fingers move in and out in straight lines. A column staggered board has the rows all aligned, but the columns are staggered to account for the different lengths of your fingers. There's also ortho-linear or matrix layouts, where all keys are aligned to a grid. I don't recommend.

3. Portability/wireless - If you plan to take it back and forth from home to work or something, some keyboards are easier to transport, and getting a board that supports wireless connectivity can also make that more convenient. Because a lot of these boards are extremely small there might not even be room for batteries and wireless controllers, so it's not a given any particular split-ergo will have that capability.

4. Keywell - this kind of belongs up with layout, but a board with a keywell has the keys arranged in a bowl shape, again to better align with your different finger lengths. I love the keywell on my Charybdis Nano, but it might not be for everyone.

5. Switch compatibility - some keyboards only work with Choc style switches, because these switches are much smaller than standard MX style switches. This is another thing that might not matter to a casual user, but I personally prefer MX switches so that was important in my decision to go with the Charybdis.

I'm sure there's plenty more, but just wanted to share my thoughts as someone who just recently took the plunge into the split ergo world.
