In general, that is going to lead you to a pump rather than semi-auto. Semi-auto are simply more complex and thus higher cost for the same level of quality and workmanship.
I love my Mossberg pump. It has never hiccuped on me no matter what ammo I've put in it. I'll admit I did buy the pistol-grip only model 'cause I thought it looked cool. Yeah, looks cool, dang near impossible to shoot well - real life isn't Hollywood, imagine that. I bought and adjustable stock for it - much better.
Have a 500 myself
Looks to be about a $50 difference. I can handle that - just can’t afford a $400 or more gun, at present.
