About six months ago I bought a nice (although not quite that nice-almost) used 870 RS, 20" IC w/sights for $175. It's a shootin' machine, and will keep three Federal full-snort (1600+ fps) slugs on the palm of your hand at 75 yards.
I gave it to my daughter for her birthday; she just got TDY to Alaska with USAF, and I wanted her to have a suitable 'picnic gun'. She can shoot it well with slugs, too.
Slick as it is, that shotgun is too high Doug.
