I was a member of MFUK for a couple years before it went down, and I got 2 copies of a really nice IS one, the Dreadnaught. Will have to dig it out but the stats were nice: Introtech 85 tonner with 3/5 speed, max armor, 2 AC/10s, PPC and 4 Medium lasers. There was an upgraded version that went 2 Gauss Rifles and an ER PPC called the Monitor, and then a third version called the Full Metal Jacket, but I can't remember the stats off the top of my head.
