Slightly old technology

I am in need of a 1/4 inch 4 track (1/4 inch 8 track would work also)tape recorder capable of taking 10" reels.

I have a cast recording of a musical I made last century and am wanting to download it to my PC to try a re-mix.
I recently listened to the master and thought I could have done it somewhat better - I had severe time constraints with regard to the hire of an echo/reverb unit when I did it back then and my "ear" has since become more discerning.

My budget is non-existent as it is purely for my own satisfaction.

Any ideas.
