I regret selling my first pair long ago and ended up getting my new pair for an inflated price. The dmg difference is noticiable though not by much if you use Sun Rings. On the plus side if you get these for an inflated price then its expected to sell for the same or even more than you paid when your done with them.
I got this ring for 650k about a month and abit ago, i think it is a very good ring, but its 800k+ now and to me that is to much 500-600k maby but if ya got the money get it, it will last a long time.
