Yard store dimple dies worked fine for me, and that's what the majority of my plane was built with - until I borrowed a buddy's Cleaveland dies. There was a noticeable difference in resulting dimple quality. Neither are bad, but the Cleavelands were clearly the superior tool and left a crisper, better looking finished riveted joint. If I ever build another RV, I'll toss the yard store dies in the bin and buy new Cleavelands. The difference in price is next to nothing, in terms of cost per hole.
