I have received my skin from gelaskin this morning (dutch time
).
Since I'm left handed it made more sense to have the tabled side of my PE on the left, so I custom made a skin with an artwork from their collection (I had to turn the artwork upside down). It was really easy! You can upload your own pictures/designs or use artwork from their collection, but you cannot mix different artists together on one skin.
Since I live in the Netherlands and Gelaskins is Canada based they said it could take up to 20 business days to deliver my skins. It got here in 6 days (from the day I submitted my order). That was 4 skins including 2 custom made ones (I ordered a one for the psp and 2 as gifts as well).
Getting the front on took a bit of fiddling, but once I got the hang of it the back was easy!
I'm very happy with mine, and would definitely recommend them
I hope you find a cover/skin that suits your needs
