Nah... some of those EOtech (aka Expensive Bushnell) holo-sights would cost more than the gun!
I was able to keep the cost reasonable:
$299 Rem 870 Express 12ga
$109 Knox Blackhawk Stock
$34 Aimtech ASM2 Mount
$23 Tight Wad Choke
$65 Barska Electro Sight (hehehe, who knows, the whole thing might fly apart with the first recoil; we'll see...)
...with tax/shipping/etc it came in a tad under $580.
OK, so maybe the stock was a little extravagant, but it's awesome!
