Well cubensis, that was one of the latest models that was giving me trouble. I was wavering between the iGramaphone, and iTurntable, and the Cowon D2.
From what I've read online, the iTurntable is a pretty kickass model - weighing it at only 20lbs + the weight of the receiver and speakers. It even beats the iGramaphone in terms of storage space, with swappable 33 1/3 rpm albums clocking it at under 1hr per album (lower capacity 45 and 78rpm albums are also available).
On top of that, from what the research I did on the iTurntable (commonly referred to as simply the iTable), is that it makes a great companion for jogging as well, due to its anti-skip technology. The only problem of course is that while jogging with the iTable, you have to be within cord's length of an electrical outlet.
Lucky however, I found something that would be a great compromise between the D2, iGramaphone, and iTable - combining all their awesome features of portability, storage space, and sytle.

The iBox
Crank powered to ensure for maximum playing time.
It also features your granmother's favorite tune and plays it over, and over, and over again.
Super portable, and no need for headphones, or even speakers.
