The T1 knock-off looks quite nice. I had a chance to look through one that another felling shooter mounted on his AR. I would say that glass is quite blue tinted compared to T1 that I have. The glass is definitely not as nice... but hey it's like 1/6th the price I think....
I also got to look through the Bushnell red dot the TRS25 I think, it's tinted EVEN MORE so I'd say try the PA one if you do not want to spend the money on H1 or T1.
