I've ordered the one advertised for 7" tablets, from an alternative seller seeing as, as you suggested above, your seller is away http://pages.ebay.com/link/?nav=item.vi ... 28&alt=web
As far I can see the (when in landscape) height will be fine. Your link was advertised for use with galaxy tab 2. The width (landscape) of the sgt2 is 20mm less than the linx 8.. So 1cm excess either side... I'm sure it'll be a snug fit, if it does fit..
I'll let you know the outcome when it arrives on wed / Thurs next week.
