I built an Iris split ergo keyboard, and it's great. Most of the cost comes from the switches and keycaps (I used Zilents and a PMK set), but honestly spending a lot of money on something I probably spent >10 hours touching each day is totally worth it.

It also takes a while to get used to the lack of keys, particularly arrow keys, and various brackets for programming. However, training myself to use layers rather than moving my hand around to push them makes me much more efficient. I plan to move to a design with even fewer keys, and since the switches and keycaps can be moved to another board, it won't be as expensive.

Also on an Iris (this very second) having moved from a Let's Split. I'm a HUGE proponent of hold/tap for modifiers and programming brackets. All the ones I use most are under my thumbs with that change. I actually have symmetric modifiers on the thumbs because I effectively have double the keys. Also all my layer changes are from holding down F, D, or S which turns the right half into (respectively) arrows, numpad, and symbol pad.
