One trick with the 4-pack resistor is to realize that you don't have to solder all 8 contacts separately. The ground side can be one big blob, only the side that goes to the LEDs needs to be done carefully.

Oh, and if you do decide to take me up on it, plan on it taking a while. I did mine in about 6 hours as I recall. Yours will probably go quicker, but no guarantees.
