I have 7 stud finders, the two best are the cheapest Zircon, it's old now, and the Franklin 710 or it's equivalent, there are clones, I got mine at BJ's. I have a blue clone I got from Costco. The company took the design from Franklin and was sued for it, and lost. I've had the cheapest Zircon $15, $25, and a $50, the $15 is the best. I also a different brand that detects electrical and pipes.

Ditto on the Franklin 710. I have that one and it is great and super easy to use. My buddy also has the Costco blue clone and it works the same or seems to. I also have the cheap magnet one that aligns to drywall screws and is fine where accuracy doesn't matter because it is only as good as the screw it is aligning to (could be on the very edge of the stud).
