Not to knock Comair, they are probably equalled only by Flight Safety, but if you intend to fly in Europe, just buckle down with a reputable all European school and plug away. You'll save money or at least break even when you factor US living costs and very poor pay and you'll get to be nearer to friends and family.
I think I have become a better "stick" and experienced pilot flying in the US, but If I had done my training in the UK, I would have been flying for an airline at least three years earlier and saved myself a lot of financial heartache. No matter how you approach it, your financial investment in your training will end up being the same whether you went to BAE or a smaller school. Might as well go to a unquestionable JAA school, with clear time and money details
Comair has been advertising it's JAA program for months and nothing has yet to materialise. It's all a bit of an unknown. Western Michigan is probably the best US option open to the "public".
Best of Luck
