25 watt is all you need for under pf work. Just pick up a screwdriver tip if ones not incl with the iron for better heat transfer when soldering larger connections (coils, etc).

Also don't forget to get something to clean the tip (i prefer the brass sponge thingy, others might say wet sponge to wipe tip on), some flux, desolder braid, crap like that. Sayal - if you have one near you has everything you need in one aisle.

I use the Weller 35W Pro and it works great. I can't speak to the quality or construction of the Weller standard duty one in the pic but the LED's i think would be handy. TerryB's guide to soldering is a good read on this forum and is what inspired me to get the hakko 888D soldering station for board work. Probably one of the best investments i have made for the hobby but never needed it for under pf work.
