Pretty much to the point (sadly), good post
I can add this, i'm in Belgium, have a verified Paypal account (and yes it has currency in it), but nothing will go through the Lindex without adding an actual credit card. So thats not an option either, which leaves some rather unsafe US type creditcards with whom i've had headaches before.
On a side note, even if you have US$ left in your SL account and you try to buy L$ for exactly that amount or even less it gets declined. I thought i'd at least would be able to buy up the US$ to L$ to give away to some old friends, but not even that works.
