What are the best e-readers with screen size 8 or 9 inches (so not the big Kindle) ?

I saw that with the software Calibre (http://calibre-ebook.com/), you can easily convert comics formats (cbr/cbz) into ebook formats such as LRF or EPUB. So I'm interested to buy an e-reader for comics reading but I tried with a 6 inches model (the SONY PRS-600) and screen is way too small. Kindle is too large, so I search one with 8 or 9 inches screen, preferably with the e-ink pearl technology for the screen.
