classic 900 turbo - LPT or Full pressure?

[1750jb]

So I would like to buy a classic 900, but am not sure which model. We had an LPT aero when they were current and I remember it fondly, but I was a teenager, so everything was brilliant anyway(!)
Is it worth the wait to find a good full pressure model, or is the non-turbo a decent drive for less than half the money??
Oh, and how exactly do you identify a full pressure turbo car?
Thanks /
