Help choosing a light and mount for 590A1

I'm hoping you more experienced and educated members can save me a lot of trial & error, cost and headache with regard to choosing a mount and light for my Mossberg 590A1.

Although I would like an intergrated forend light, I just can't bring myself to pay almost $300 for a light that may never be used on this HD weapon.

I've done some looking on Optics Planet and Amazon. Just when I'm leaning in one direction or another I read some reviews that have me hesitating to make a purchase.

If someone with first hand experience can point me in the right direction of a reasonably priced solid, reliable mount and a super bright light that I can activate with a pressure switch, I will be most appreciative.
