Anybody experience with selling your app to appholdings.org?

Has anybody experience with appholdings.org ?

On their website they are offering “We can generally offer around 6-24 months of last 30 day’s revenues and can purchase apps & portfolios in the $5,000-$1,000,000 range.”

Has anybody sold an app to them already ?
What prices do they really offer?

Hey everybody, back when we were looking into selling to appholdings I read this and was hoping for a reply but no body ever did! So I thought i would reply for anyone else wondering. We actually ended up selling to them and it worked out great and they pay what the say. I think we ended up getting around 15-16 months of last 30 days revenue, but im sure it depends on the app.
Good luck I recommend them for sure!

Maybe this is not the most appropriate thread for this question, but can someone advise how to sell a mobile app properly, what is the best and safest way to arrange payment and transfer of ownership?
