Thansk for all the replies!
I'll be looking in to many of your suggestions as soon as I find the time.
Here are my thoughts at the moment.
P2006T - None of us are multi-engine certified at the moment, I can get my done fairly quick, but the other pilot is just getting his PPL and a twin might be a bit advanced to start with. Also, I think it's a bit out of our price range.
DR400 - Haven't looked much in to it yet, but it sounds like a good options from many of you here.
Cirrus - I would love to own a cirrus and will look in to that as well. Only problem is I've heard a lot of negativity about their doors.
DA-40 - One of you suggested the DA-40 might be an option. A guy at the local flying club also suggested it. Any more thoughts?
C182 - I'll look in to it as well. Problem is, I don't like high-wing aircraft. Maybe I'll get used to it.
TB20 - Haven't had a chance to do much reading on it, but I found a massive owner write-up of it online and will read through that when I have the time.
