I just had a chance to check out a TA-01 yesterday, and I was impressed at how bright and clear the optics were in such a small "scope". The extreme right side of the recticle (only the horizontal main crosshair) was blurry, but I hear that that's pretty normal, and it didn't bother me at all. I like the recticle; it didn't seem quite as busy as the TA-01NSN recticle, and I like the full red illumination, too. Let me put it this way; the thought of spending that much cash for a sight makes me cringe, to say the least, but I'm not going to even bat an eye to get an ACOG for my rifle. For a small, light optical sight that'll be around for awhile, ya just can't beat it. IIRC, it's around $35 or so to get the tritium replaced (now anyway; by the time it needs it, the price will have jumped up to $500, knowing my luck). In my opinion, the only thing the ACOG needs to be my perfect sight is flip-up lens covers (I hate the cheesy "bikini-type" covers), and if they could just lower the price by......say, $5-600, that'd be great.
