I have 4 and planning on another here in the next few weeks.
1-upper right arm (eagle - you can see in profile)
1-calf right leg (HRC symbol with a dear friend's name underneath who has passed away)
2-tribal designs on back that i designed (again, you can see in profile)
my next one, i designed as well, the Scottish lion inside my family crest with a crown above it - going on my upper left arm
i don't think i'd ever get an armband for one reason only. I think it only looks good on guys with 18 inch arms.
however, i do believe you need to make sure the tattoo you want, "means" something. it took me almost 2 yrs to get my first tattoo - i wanted a bald eagle with an American flag (i come from a military family and served 10yrs myself) - finally I found exactly what i was looking for - haven't seen anything like it since.
i vowed after the first one, i wouldn't get another... 4 tats later, i'm getting ready to get my 5th. it is addictive - but you have to be careful what you PERMANENTLY put on your body - you have to live with it.
My suggestion, find something you like, or design something yourself - then sit on it - look at it daily - and after a month or two, if you still like it - GET 'ER DONE - if not, find something else.
