get the wilde set from epstein's or an old channellock 907 if you can find NOS or just pick up a used one... i've been very happy with both of them. the wilde set has a little larger selection of tips, but has separate tools for internal and external snap rings. the 907 is a one tool convertible. bonus is the wilde and channellock are compatible with each others tips.
i am _not_ happy with the new channellock retaining ring pliers, that replace the 907, the 927. they do not feel well made to me. i wouldn't recommend those (don't own, just tried in store).
