Which Nakamichi to choose?

I had a CR 7 and a TD 700 for car that gave me a lot of satisfaction; the CR7 sold it years ago because I had not used the cassettes for a long time, it was still new with all the bundle supplied.
I made a buyer happy.

I could choose a tape deck now I would buy Naka again but prices have skyrocketed, an exaggeration.

I still have my (prized) Nakamichi TD-700 mobile unit.

I also kept the TD 700 bought over 30 years ago and revised in 2005 to put on sale on ebay, but I did not have the strength to do it and is still with me, I'll have to decide to do it sooner or later.

I gave a ton of cassettes away when I concluded the medium was antiquated.

I did the exact same thing when I sold my Naka, also give away many sealed.

But I made a mistake by committing ingenuity, now the cassettes are sold at several dollars on new ebay or used especially if of high quality.
