Travel Ergo Advice

Hello all:

I am in need of some advice. I am a consultant for a living and spend my days writing reports. When I am at home, I am using an Advantage 360 Pro which I absolutely love; when I travel to meet with clients though, I use my corporate Mac... which has less than stellar ergonomics.

The 360 is too big and bulky for me to travel with (I know some do), but I use forearm crutches and need to carry everything in a backpack. Weight and overall size are an important consideration.

I was looking at the Glove80, and the Corne-ish Zen but then I saw the new ZSA Voyager...

I also thought about something like a Skeletyl, huge fan of the Dactyls - and the work over at BastardKB; I love minimalist layouts but I also live in Canada; the 360 with exchange and duty when I ordered in on Drop cost me ~$750CDN.

I wish keyboards were more affordable but hey...

Thoughts?
