The Titanium Band is by no means a piece of garbage and will last you as long as it takse for you to get to Sandworn and collect 25 badges. Keep in mind also the fact that there will be epic gems in game soon and the gem slot does get better when that happens. Still, I think the other 2 are better but you're not gimped for holding off on the Sandworn whilst spending DKP on other things.
your hat may be nice, but I have the little white tank top that says Legendary right across my boobs. I win. (or more correctly, H wins)
