If e-ink e-book devices aren’t your thing or if you are looking for a smaller, pocket friendly device to read books, consider a PDA.  Get High Tech has refurbished Palm T5′s available for $99.99.  Here are some the features listed:

•  Palm OS® 5.4, 416MHz Intel XScale416MHz Intel XScale, Extra-large 320×480 Transflective TFT color display supports more than 65,000 colors in both landscape and portrait modes.
• 256MB (215MB actual storage capacity: 160MB internal flash drive, 55MB program memory for applications and data.)
  Supports SD, SDIO and Multi-Media Cards
• 320×480 Color Display
• Bluetooth® Wireless

I have a T5 and from what I can tell it has everything the TX has except the T5 doesn’t have integrated Wifi.  I have never purchased a refurb from this site, but I have ordered parts. As with all purchases take care and call/email  the store if you have questions before you buy. I think that at 100 bucks it’s an inexpensive way to dip your toes in the water.
