Don't forget to look at the Mossberg 500 and the Win 1300 either. The way the prices are around here you can get either one of those, plus 3 choke tubes and a couple hundred rounds of ammo for the price of just an 870 with modified choke only.
I'd say handel them all and buy which one feels the best to you. Of the 3(and I own the Moss 500 and Win 1300) my favorite is the mossberg because it fits me the best and I like the saftey position on the tang rather than the trigger guard. But then again thats just me.
Sincerely,
Adam
