I've been installing lots of crown molding with an 18 gauge brad nailer and have been putting off the purchase of a 15 gauge finish nailer, until recently. I decided to go with the best and bought the Senco FP 41XP. I am very impressed with the engineering of the gun. It is well balanced, lightweight, silky smooth and fires reliably without leaving a mark. I highly recommend the Senco FP 41XP (too bad I bought my gun before Amazon decided to throw the FP15 gun in with the deal).
