Brand, Model choice...

[Big joe]

I've become real interested in a serious air gun. You all who know about these guns can maybe help me decide on a purchase.

I want a rifle that will give me at least 1000 fps with 177 cal. I want to acheive that with only "one pump".I want something with good to great accuracy and finally... I don't want to break the bank! Also I need to know if a rimfire scope is ok on it or do I need a special scope for an airgun...

Any info you can give me on brands and models to consider would be greatly appreciated!!!

Thanks
