Red Dot For The Money Red Dot Scope/sight Troubles?

Red dot scope/sight troubles? - red dot for the money

I am looking for a red dot scope / sight I can put in my gun (it's a weaver / rail piccantary) for USPA CESPI and practices were. I am new to this sport and I want the best for my money (less than 100: [). I saw a few facts and models.
Note: Your creation of a buckmark, 22 LR Browning.
AND ALSO .. Which is better, a panoramic or "tubes" for this type of sport.
