DIY is the best route, and a pin tool, or even a mini tool-kit off the Bay will set you back less, or the same, as going to someone.
However, way back in the day before I had tools, I had good luck with "Department Store" (that does not carry the same brand) watch repair sections. For example, to this day there is a "Sears" with an on site watch repair guy. All he does all day is change batteries in Quartz watches. These guys see reps all the time and can care less.
Should you be called out by a Kiosk or the Sears WIS, just be agreeable: "I thought so, my brother-in-law gave it to me and said he got a "good deal", now I know why".
