My two pennies:
Suunto is still very popular, so it has good resale value. And it has great design. Most of their stuff just looks very good, especially their watch-sized computers. The competition invariably comes up with piss poor design watches.
I have been browsing for a new computer in the past few weeks and was close to digging out 750 Euros for their D6i Novo zulu, which looks kick ass (I think).
But then I slept on it and realised that I had forgotten what I'd started out doing in the first place: finding a dive computer with value for money. And in my opinion Suunto is anything but that, even here in Europe where Suunto products seem to be quite cheaper than in the US.
To be honest I think they have started lagging behind a bit. If you look at their new line of products, it's just the old stuff with a new lick of paint and the word Novo added (the irony!). Except for the Eon, which is new, but not really a winner, so it seems.
If I were you, I'd try to get my money back and take your time to look around carefully, checking for good second hand deals. But that may not be possible in this case, so you'd be bound by what your LDS has on the shelves. In that case make sure not to confuse what you want with what you need.
All that said, the D6i is a pretty looking watch of course.
Good luck
