It really depends on what you're looking for in a reader.
For eink, the Kobo is rock bottom today.
You might find a Sony 300 in the same price range but odds are not much else new.
Keep an eye on ebay for Nook refurbs.
If you do a web search you'll find the Sharper Image literati at $69 which isn't bad (essentially a Kobo that trades off the virtues of eink for those of color LCD). Not the $39 of last month but it's a fair price for a competent enough connected reader.
If compact size matters more than format support, the Jetbook mini is often found in the $80 range.
Things should improve by late summer if the K4 materializes and pushes prices down lower but right now...
