Obviously this is entirely your decision, but since you asked: I would wait. Not necessarily because of the reasons you listed, but so you have time to really think about the tattoo. This isn't something you want to rush into. Get to know some artists' work (in your area and abroad), look for inspiration not just on the internet but in tattoo shops, books, etc. Then go and get the tattoo.
