IO540 not to my knowledge, at least not at present. I'm in a similar position (re CPL) and know the scene there pretty well. The thing is that since the introduction of JAR the US licenses have lost a lot of their luster, unless you fly your own N-reg a/c, as I believe you do. Some countries (e.g. Austria) have even discontinued their 'Certificate of Recognition'
Wanderer not sure where you got your figures from, but their website lists something like € 84/hr for a C150
excludling landing fees if buying a block of hours and paying in advance.
Aerodynamics Malaga will rent you a C150 for € 94/hr
including landing fees, again if you buy block.
In both cases, the prices of course go up with bigger/faster a/c, but are pretty similar if you factor the landing fees in. For whatever reason, Aerodynamics have decided to include them, whereas F-i-S do not. At the end of the day, much of a muchness, really.
