I'm currently discussing the idea with someone in the states to host mine for about $15 a month for a BFL-SC-Single.  Which cost $1,300 so at 20% VAT then that's $260 or just under eighteen months of $15 a month.  An due to Moore's Law after eighteen months new ASIC then should be twice the hash-rate so you'd probably want to upgrade.  This person has also said he will set it up to Merge-Mine on P2Pool or provide full remote access.  So good for the network health in using P2Pool.  I'm just waiting on a legal letter for piece of mind.
