It pains for me to say this but you can pick up some bargins now. You maybe lucky and find one that has had its belts done and just requires a bit of tidying. Or a really nice one that needs the belts doing. Keep looking in all the usual places, something will turn up.
I am not sure if you are looking for a 120 or a 180, but here is what can be had for 1500 quid. It is such a shame these cars are now going for silly money!
It isnt great the prices they are attracting, but at least it means that there are plenty about for the enthusiasts out there, maybe even 2 if you fancy it haha!
