I really think the Ares ETR is the sweet spot at this price point, but I personally have seen 3 out of the 5 in my group I shoot with have issues (they all got them at around the same time maybe it was a bad batch I dunno....) of course Athlon fixed them up I'm sure but still no way in hell I buy one online without actually laying my eyes on it unless I really and I mean really get a good deal or am in no hurry whatsoever.
I have used several of the Gen2 PST's I think they are an excellent scope for the money and for the excellent deals floating around on them very tough to beat. They are absolutely all over the range I shoot at and have never heard of or seen one with any issues. Im about 90% sure thats the scope I will use on my budget build I am working on right now at least unless I can find another screaming deal on a used Cronus.
*Edit* I know this sounds like I am anti Ares but honestly its the best scope imo in this price range feature wise and glass wise. Just lay eyes on the damn thing before you buy it, shoot it see if it tracks then enjoy the damn thing.
