Just get a newer Kobo. Any model made in the last 10 years will be an improvement. The lighted screen will likely be somethingyou'll appreciate more than you think.
I'd recommend the Clara 2E due to it's small size.
If you want to save some money, you could go for the Nia. Usually the cost difference between the Clara and the Nia is so small, I'd say go for the Clara. But looks like you can buy a refurbished Nia for
$80 on Amazon.
The Nia and the Clara are both similar enough to the Touch that you likely won't notice much difference.
