Hey Andy No i wont compare a projector to a car make or model,
I have always simply been more than happy with the HD1200 purely as it has great sound and light output, very reliable, and of course, (for us), i am fairly lucky to have a few essential spares which have kept my films scratch free, any marks on our movies would have been there at the time we bought them with the exception of two shorts, (the single faint black line to the very far right), I soon had the machine sent to the Elmo King , our Billy, after realising it wasn't being caused by any of the green guides, and he picked up a worn sound head pressure pad, we managed to buy two brand new ones, the full assembly containing the four pads and springs, from Leon in the USA. Took a while but all in and hopefully will last another 30 years.
I always fancied a GS 1200 but as already said, you do need to have some experience of electrical know how and ability about you to be able to repair and maintain them yourself. I dont do anything other than the very basics of electrical work. Aside that, while they are very good machines once they have been modified they are, (for my purpose) too over engineered.
