I'm sure most will not like this, but here is what I did for a cover. Rather than pay $35 sight unseen for a new cover, I picked up a 300 black Sony cover. Best Buy has them on liquidation for $9.99. I simply removed the spline attachment used to hold the 300 in place and used double back tape (or you could use velcro) to secure the 350 into the case. Sure the cover is a bit big, but it still looks nice and functions very well. I'm able to hold and use the 350 a lot better than without a cover.

BTW, I almost ordered a 350 cover from Sony, but after looking at the photos of the ugly pink one I could see the design looked cheap and thin compared to the sturdy and quality built 300 covers.
