The Handspring Treo 300 now has $200 worth of rebates on it directly from Sprint (up from $100) as noted by Gizmodo.
The PDA which sports a color screen, keyboard, and PCS connectivity can be had for just $149.99 from Amazon.com with a new service activation from Sprint.
If you do not buy it at Amazon.com, expect to pay around $300 as Amazon is tacking on an additional $150 rebate... But only if you plan to move quick--the Amazon.com rebate ends on April 9th.
