I have planned for the C150. I suppose it comes down to availability in the end though doesn't it. I normally fly PA28s in the UK but that is to go with friends and family. 75hrs on a C150 comes up at €8475 and then when you take into account landing fees and accommodation it does add up especially as its 75 landings if not more at around €15-20! Then there is accommodation and flights to and from Jerez. I think the planning of all the flying training is just important as the training itself.
Good luck to you also my friend!
