Hi ddesigns,
It may have sold for more last year, however LLLL.nets have fallen quite a bit from their peaks of February 2008. As for my regfee comment, it is based mainly on the fact that at present most quad premium LLLL.nets do not sell for more than that. Yours is a good combination and I could see it selling for an equivalent amount to that of an average quad premium -- that amount is about $3-$6 depending on when the domain expires. I assumed that yours was either a fresh reg or several from expiration -- it may sell for less if it will require renewal soon.
