Any experience with this or the Truglo 30 mm red dot? 

The 20 mm model is on sale now at DSG Arms for $69, which seems like a good price.  I've been looking for an inexpensive red dot to play around with on an AK and possibly on an AR.  I already have Aimpoints on other guns, so this one is mainly to test and range fun.  Of course, I don't want a total POS, but I am not looking to spend $400-700.  The main competitor is the Bushnell TRS-25 and Primary Arms Micro Dot, though it seems like Primary Arms red dots are seemingly more difficult to find these days (at least on Amazon).
