I am in the same boat as tattoo with pliers. I seem to go thru about 5+ per year as well. I bought some "stainless steel" pliers from someone at the SB show...they were like 15 bucks and looked good. They must have been the cheapest SS pliers in the world. By the 4 trip they were pretty rusted. By the 6th trip I couldn't use them with one hand and I thru them overboard. Dr. slicks...are good for one or two trip...way to light, aimed at the FW river flycaster IMO cutting 2# tippets, I tried cutting some twisted briaded wire and the cutters took an indent. The Cheppo hardware stores rust befor you can get them out of the shrink wrap and your right about the job lot ones these seem to seize on me by the second outing.
So last season I picked up a pair similar to what you have shown (Donmars in stainless). They actually lasted a season and I left them on the boat exposed. But they cost me like 169 and I am afraid to drop them overboard and always keep the teather on. I have to say they work very nicely but they are too expensive. They told me if anything *ever* has a probelm and for 35 bucks they will either repair or replace them. I know of two folks that sent them in for a minor thing and they sent back new ones.
Problem is I need more then one pair of pliers...I need like 4 (beach/truck/couple for the boat) so last year I picked up several shimano's @17 bucks ea. They have a Ti coating and seem to last a little longer then bare steel. And when you drop them over the side you don't feel the pain in your wallet, you take out another pair.

While it is nice to have these great costly donmar pliers, you need more then one.
I want to look into these new "floating pliers" that people say can cut braid like butter. They are cheap too.
