A local store has new Harmony SST-748s for sale for $40. I saw some reviews from 2003. This was a product from Intrigue Technologies prior to Logitech's purchase of Intrigue and is not current, obviously. I notice that this item is not on the Logitech web site. It has very few buttons and uses a scroll wheel and the display. The price at the time it was new was $200. Has this thing become obsolete or is there some other drawback? Is supported by Logitech or is it an orphan? Is it a buy or a dud?
