I am not as worried about the length of the warranty as about the location. If it works in my country (as I know some electronics have warranty so you can get it serviced only in some countries).
As for price I am willing to pay 125 $ but only worth it if really will be good. I am sure with time if I like using ereader I will buy more and won't be so careful and cheap

.
I will have to check out your suggestions. I need to figure out the delivery too, I saw Amazon shipping is cheap (at least the written info in shipments info). Wouldn't want to pay another 25 $ or so on shipping.
I think since my bad luck with electronics I prefer quality even if it means worse user interface (I mean less shiny but lasts longer). I need to break the spell of stuff malfunctioning around me
The most important is that ereader would be
good for eyes, good
survival skills in my hands (I don't mean surviving dropping or anything similar) and the total shouldn't add up to more than 150 $ (everything included - shipping, case if it is necessary). For good user interface I could pay a little extra. But in my experience sometimes it is better to buy simpler product - more reliable.
Update: checking now and can't seem to find where to buy Kobo touch outside USA and Canada. Looks like only wifi version is available somewhere else and still not in my country. UK closest
XOVision appears to not be e-ink. And the main reason for ereader are my bad eyesight.
SKYTEX not e-ink too. From what I read so far
So far it looks like it is either Kindle or Nook. I am just not sure about Nook warranty. I might be confusing it with another ereader but heard it is troublesome to get warranty service if you are from some other country. Just checked and it seems that Nook is only for USA. That's the main reason I had to dismiss it. A shame your choices are limited because of where you live
