So it seems my alternator is in intermittent failure mechanic says probably the voltage regulator. I was looking around and i saw just the regulator as a part i was wondering if it was worth it to try and change out or just the whole thing i will admit i am trying to save some money

If the alternator is not making bearing noises, it's a way to extend its life.
New regulator might be easy to get to, and swap out; also get new "brush holder"
How many miles on the car?

Since the problem is currently gone, you might want to forget about it until it returns, or the weather gets warmer.
Buy a cheap multimeter, $5-$8 at Harbor Freight, check voltage output, needs to be above 13-13.5v and should be about 14.5v. Look Here for discussion: LINK
Edit: Noticed your mechanic says probably regulator - check eBay Here

At 156k -- if it's original -- bearing can be worn, ditto for brushes. (Did following myself, on a BMW with 110k where lights would dim & flicker at idle) IF you can easily get to the alternator, disconnect battery and remove alternator. Disconnect and Clean all electrical contacts - Regulator & Brushes & GROUND connection.

Brushes are cheap - around $15-$19 delivered from rockauto

Think about changing brushes, but first clean everything up, which cured my problem for 5-10,000 miles.
Again, if the bearing is going, as-in making growling noises, LINK, you want a new/rebuilt alternator, since doubt you want to remove and press in a new bearing.
