Oo oo my fav subject
A little bit of experience - I built the Maintrack T10 conversion a fair few years ago, and this is God awful. No interior detailing what so ever, but that is out there too on Ebay.
I have the Heritage T8 in 1:48, which is built awaiting some cockpit detailing. (see link below I posted on ARC early last year) Not bad, and I would recommend this.

I also have the Heritage T10 awaiting to be built. Heritage conversions aren't bad (given they are/were the only option) and they do have some interior detailing too - but of course a little styrene here and there and it would look half decent. The ALITALIANE version, I have only seen on the Internet. Shaun started a WIP thread on ARC...see below, and this uses the Alitaliane conversion.
