I'm surprised that the Ronague farmhouse is seen as expensive by you (though the dollar appears to be in freefall and accomodation/food/service in Europe is always seen as expensive to Americans). There may be cheaper places - eg most coach parties stay at the Cherry Orchard in Port Erin - my brother stayed there and reported it as perfectly acceptable.
I don't think anyone on the board wished to be rude towards you - brief non person-to-person communication is always easily misunderstood. I'm sure you would enjoy a stay on the Island though I suspect October in Kk Michael would not be not quite as warm as the southern USA - after all the Island is further noth than much of Canada.
