Believe me, they are no longer available and haven't been for some years. It doesn't matter where you live, they are not available.
Hence , mint examples of any item in the series fetch premium prices. The only possible exception could be the cassette player which has a limited market nowadays.
I have two mint mint turntables for sale and two very good turntables at half the price. The only real difference is the quality of the lids!
If you are desparate, you can purchase a 3500 series component, remove the lid and strip the paint!! 3500 series is cheaper than 4500.
This has been done by one of our members, although I have not seen the result.
You may find a dealer, somewhere in the world, who ordered one for a customer who never returned to collect it. On the other hand, you may be able to find a needle in a haystack!!
