Hi folks!

After more than 500 books and 1000+ hours of reading on my Kobo Touch, I dropped it and cracked the screen, rendering it unusable.

As a result, I'm looking for a solution to keep me going with the ebooks on my list.
I have a few options and limited budget (not more than £70)
I loved the fact that Kobo supported Epubs, and as a result my current library is loaded with a few hundreds e-books on that format, so am trying to find a device that supports that format, as I assume it would take ages to convert those e-books?

So, here are my options:
1. Changing the screen. Costs about £30 (the price of my e-reader back in 2013) but limited functionnalities compared to current models
2. Replacing the Kobo with a Kindle. Would cost me £60 at current Amazon prices for the baseline model. I don't need the Wifi or 3G as I'm old school and transfer my books from the PC :-)
3. Splurge and replace my current Kobo with the Aura or H2O versions (£100-120), but I'm unsure whether it would be worth it given how long my Kobo touch lasted.
Any thoughts on this one?
