No. I've never bought any razor with the idea of selling it if I didn't like it, or with the idea of selling it at all. I've bought three NOS injectors, (Personna, L1, and O), opened and used them all. Bought two NOS DEs, (Gillette G1000 and late model Tech), actually haven't gotten to the Tech yet, but I will.
Some people feel very strongly that you *shouldn't* open an NOS razor. It's no use arguing, but that's not how I see it. On the practical question of resale value, I can see that if you got an NOS item at a ridiculously low price, there would be a temptation to leave it unopened and turn it around on eBay for a profit. In the end, though, it's going to be purchased by somebody who just wants the razor. If that person is me, it's going to get opened.
[EDIT] Adding one thing on a related issue, it is possible for a blank blade to be re-inserted in a used injector. I've seen this with a couple of my own. You only know it's unused if it's in sealed, tamper-evident packaging.
