^Most ebook readers are priced in the 4-6k range, mataas na yung 7k ata for 3G readers. You can google for comparisons between the top brands (Nook and Kindle), pero meron din namang ibang brands that you might also like, tulad ng Kobo, Sony etc.
Madami online reseller sa tipidpc, you can just do a search for Kindle there and you'll see a lot of them selling Kindles for a little over its retail price on Amazon. Just pick the most reasonably priced from a reseller with good feedback. I'm sure meron din resellers for other brands.
