I'd personally not look at a T67; the safety record of the small engined versions is poor, and across the fleet they all seem to spend a lot of time stuck on the ground whilst waiting for the parts to address yet another Slingsby AD.
I think that the Bulldog is worth a look - there are a number on Cs of A, great aeroplane to fly, very robust (plus all metal), and quite appealling because of the military history. Bargains are to be had buying a non-aerobatic one, then getting the spar mod done in-house to re-enable aerobatics.
