Heck, if you had gotten it from them, the guys at the 2 Batteries+Bulbs stores near me would have probably done the solder work for you too.
I wish I had a little work station as nice as theirs is to do that stuff. Radio Shack is 2 buildings down from both of mine. I've literally gone from Radio Shack to them & had them do the solder work for me(yep, lazy). Most of the guys will do little stuff for free (I slap 'em a tip still though) or if it's something bigger, they'll do it on the side for you.
Price wise, they seem to be about the same or cheaper as everyone else locally, if the other place has it that is.
Just my 2 cents worth on it for you to keep in mind next time...
Pessimist: Oh, this can't get any worse!
Optimist: Yes, it can!
