I recently bought a pair of 10x42's and compared them to my 10x trinvid, Zen ED2, and the neighbor's SLC's. I put them slightly better than the trinovid/SLC, and ever so slightly behind the ED2. The GR HD's are very well built, great glass, and 95% of anything out there. I prefer them to the meopta also due to the thin eypieces on the meopta which don't fit me well. At $599 after rebate the GR HD's are a no brainer to me.
