Until a few years ago, I would have said get them (actually get the aluminium ones, if only to make me jealous LOL).
However, the landscape has changed a bit in recent years.
First, the HD25s are still around and probably will be forever. They are a very very good set of cans for studio, live sound, (post)production AND DJ-ing. There is no sound event I go to where not at least one person is carrying a pair. They are also highly popular with reporters and cameramen. Soundwise there is nothing to fault. They are lightweight and pretty indestructable. And if something does break (or more likely just wear out), EVERYTHING can be replaced (although not cheap replacements, a new cable is about 40-45 euro I think :-p ).
So getting a set of 25s is never a bad choice.
Here comes the big question though. What are you planning to do with them. If they are DJ-ing only, there might be alternatives more suitable. If (like me) you also do live sound and post production and/or studio work, it’s still the best all-round choice, imho.
For DJ only purposes, the Beats Mixr seems to be gathering a following, even my esteemed and highly experienced (and HD25 using) co-moderator Terry is using one I think. Another set to look at (although slightly more expensive) is the new Sennheiser HD-series. I’d forgo the HD6, but budgetwise the HD7 would fit. Especially if you are looking for over the ear with higher sound isolation, they are a good contender, imho.
Hope that helps.
