YAY or NAY?!?

So I decided a few months ago that I was going to go ahead and get EXTENSIONS! I have been growing my hair out for 2 months now and it is almost to my shoulders. Well, now I am having second thoughts! My friend Meg's says to do it fo sho! Then my mom says No Way! So I am wondering what you all think?? Please even if we aren't wicked tight pals, leave your opinion! I really want some input on this plan of mine!!
Here are some of the pro's and con's that I have come up with.....
+I am 30 and this may just be the last time for me to have long hair!
-Short hair is in style
+I can pull it up into a nice thick pony
-Take longer to do it, when I do it
+I can feel pretty
-I have had them before, (it was artificial and they sucked!)
+For a drastic change
-Someone asked me what my hair looks like styled the other day! (growing stage sucks)
+My friend Meg's does them fantastic!
-It might not suit me. (looks and personality)
+Only lasts a few months if no likey
-Only lasts a few months if I likey
As you can tell I am having some serious back and forth issues with this... not that big of a deal I know and so very vain BUT please, what do you think??

If pictures would be helpful I will add some later on.. I have a little monkey on me begging for "PBSkids.ord" After he is done playing Curious George and Caillou I will find some pics to post.
