Great selection, George!!!
After wanting an 870 for so long, I went to a gunshow and purchased the very same nova you have! I dunno what happened, I didn't find an 870 I liked at the show, so the benelli sort of made me buy it! It fits me okay, though I wish it could be a little shorter. I was at my local gunshop this weekend and asked about a thinner recoil pad, and they did find a couple listed in their benelli catalog. I think the LOP could be reduced to just under 14", something like 13 3/4", but don't quote me on that.
There is a side saddle for it, though we're in the same boat as the newer 870 owners in that we have to get a 4-shot SS. this gun seems to kick less than my 870 with a synthetic stock, as the recoil pad is a little wider than the 870's.
I've been to the beretta defence site, and they have the Nova Special purpose with a picatinny rail! I'll have to write benelli to see why we don't have one. Check out this sweet rig!!!

As for a fore end light, I think I'm going to go with the Streamlight M3 unit.
Things I like about the nova SP: Light weight, can eat up to 3 1/2" shells, ghost sights, magazine cut-off button (awesome for slug/buckshot selection drills), and the controls are similar to my 870's.
Things I don't like about the nova SP: Wish they offered a 20" with removable chokes, ability to exchange stocks and recoil pads with ease, and the fact that it's cheaper to buy another nova than to get another barrel for hunting!!!
