Prices are completely subjective for the most part, so it depends on whether you think it's a good deal or not. We can't really tell you if something is worth it, because it might be for one person and not for another....That being said, it does look like a very nice razor!!
I really like the Puma 89's, though not quite as much as some of the slightly heavier models (in particular my 22). They're definitely a good razor. From that picture that one appears fine... but it's NOT a very good picture, so it could hide a lot. I'd ask for much better pics before I dropped close to $100 (haven't checked exchange rate in awhile, so that's a guess) on a razor. Ask important questions such as:
Does it close centered?
Are the scales damaged or warped at all?
Will it sit partially opened or does the blade fall into the scales?
That said, if it all checks out, yeah I'd say that price isn't too bad. It's not a steal either. It's fair. If the blade is NOS (completely mint) it's a really good price. If it's just in very good shape with no real damage, it's fair.
It's a good deal if all is well with the blade. I would make sure the blade and/or the scales don't have cracks. How wide is it? It looks like an 11/16 or 6/8.
