The only cameras with DSLR speed are DSLRs, which you could get the Nikon D3000 or the Canon XS in that price range.
I am looking for a camera. I had the Nikon Coolpix 300 but now I need an upgrade. I am looking to spend up to $600. I like a decent camera with SLR speed. It will be mostly for family activities indoors and some outdoors.
