You're asking for a lot of stuff for $400, assuming you want decent quality.
I have a Leupold 2-7 ML/shotgun scope on my Knight. It's been shot maybe 100 times and I've not touched the knobs since I zeroed it. No light, no hashmarks, but solid so far, and well under $400. The reticle is very bold.
Elsewhere on this forum, there's a post about a Hawke 2-7 with a light and 4.5 inches of eye-relief for $100. I bought one, and it looks good, though it's still to be tested. You could buy 4 of those.
Natchez has a bunch of stuff on sale, some pretty cheap. You may find a suitable scope deeply discounted there.
