This thread has much win! LOL!
Some tough calls. Plenty of bullet points either way, but more for the MK6. Except price.
A really good deal for a CF-31 MK2 was offered to me also! Too many decisions to make...
My biggest problem is, I am not really sure there is a one size/model fits all needs for me here. For working ON my photographs, the 10" screen on the CF-19 is horrible. But for tethered shooting as just a monitor, its more compact size works nicely. The compactness is a BIG all around plus.
On the other hand the 13" screen of the CF-31 (or my current CF-30) is much more manageable for actually working with the photos. And the bigger, full-size(ish) keyboard is much nicer to use.
But realistically, I am not sure I can change my photography workflow and tools enough to even make using a Toughbook here possible. And thats the biggest reason why an investment much above $300, and likely capping out at $400, is hard to stomach.
I just checked, my CF-19 is actually a MK1. My CF-30 is a MK2. Both are pretty much fully loaded too. The upgrades in the CF-19 are easier to remove though, and it is defiantly the slower beast.
I just put a Best Offer in for a MK5. If I get it at or close to my offer, it will be a very good deal at half the going price for eBay MK6 models. That savings is worth the very small bump down.
