Whenever someone asks such a question I am puzzled because I don't see how someone else can climb into your own head, know what your personal needs are for a radio, your expectations, etc. Don't forget, if you need a radio there are much newer ones available, and for less money.
If this radio gives you a woody, and the purchase of it won't leave other family members wanting for food, clothing or shelter, I'd say yes, grab it! You cannot put a monetary value on personal gratification.
On the other hand, if you are just looking for investment counselling because you heard something about vintage radios being valuable and don't give a crap about the radio itself, I feel sorry for you because you are completely oblivious to the real return one can get from collecting such 'treasure' IMO.
Sorry about the rant but when someone asks this question it always hits a nerve.
