The only readers that ever had glare problems were the Sony 600 and 900. Sony chose to put a touch layer on top of the screen and that affected screen clarity for those models. They fixed that with the PRS 350, 650 and 950, so that the Sonys and Kindle 3s have the same screen clarity. The key point now is if the reader has a Pearl screen. It greatly improved contrast over the earlier Visoplex screen. The Kindles and Sonys have a Pearl screen, as do some of the new readers from PocketBook.
There's a free program called Calibre that was designed to be a library manager. In addition to letting you fix metadata and set tags, it will also convert from and to most formats and will sideload books on to your reader using your preferred settings. There's an active forum here for Calibre, with some very helpful members who can help you as needed. I've never seen the need to send a document off for someone else to convert when I can do it on my own computer.
