I have a set similar to
this . You don't have to go quite so expensive, but I will say that mine are 4yrs old and still look and work great! A quality cutter is very important, you can go a little cheaper on the pliers. I like having round nose, chain nose and flat nose pliers and use all three for most projects. Some people like having the bent nose, or even two of the chain nose...I guess it is a preference.
You can also get a special dip that coats the end of your pliers making it so they don't mark the wire, but I've heard mixed reviews. It's really all about learning the right pressure to manipulate the wire without marring it. Also, the temper of the silver makes a difference. I like half hard for small gauges like 30g-20g but anything larger, I use dead soft.
hth, happy shopping!
