Thank you for all you suggestions; they are wonderful and I am leaning to the P20A2/MKII.
May I please add one additional point. Although I currently have and use AA rechargeable, I would be open to other possibilities, like the 123 etc. However, I have never gone this route before and would need a suggestion regarding a recharger etc.
Also, I need the light to be around or under $100.
Thank you for your educated and honest help...you're great!
