I'm a big supporter of indie authors, but I've become much more selective in what I download to read.
If the book has been read and mentioned by members, I'll check it out. Of course, if I have read other books by the same author (and liked them), I'll get more by the same author.
I don't check reviews on Amazon, instead, I check for independent bloggers reviewing the books. I look for at least 3 to 5 reviews on different sites, before making a decision to buy.
