Thanks for the welcome!
The EBayer selling the 8" Lilliput is "electronicar," who appears to be the same person a lot of posters here recommend for the 7" widescreen Lilli... The EBay ad is odd because it looks like s/he recycled the ad for the 7" and forgot to change a lot of key points (the text and the pictures don't seem to agree)...
Here's a link to one in GBP...
It looks like a 4:3 aspect ratio at 8" diagonal. Other than that and the fact that it's DVI and has an S-Video input, it appears the same as the 7" version. It's only about $40 more if I recall correctly...
