i would whole heartedly advise that you think about it (duh);
decide what you want and exactly where you want it;
then wait a year. forget all about it (or at least try to)
if 12 months later, you still think the piece and the place are good... then get it!
the point is, any tattoo will exist longer than you will! and so waiting an extra year is nothing to worry about!
it is good that you are looking for a piece that is original and not something off a parlour wall, but please tell me you aren't going for the rome logo!?
Just coz you don't understand it
Doesn't mean it makes no sense!
