if the table has been active like you say, i'd push because,
a) you probably have the best hand, and you don't have that much of a stack.
b) its 7 handed,
c) an utg limp seems suspicous to me, and anyone who calls and/or raises is likely to have a strong drawing hand, or a hand thats simply better than yours.

even if the button calls you, you have a big enough stack where it would hurt to double you up.

its ok to just take down the blinds+antes for now, as you may need them soon.
