My experience suggests forget about lasers as they are basically useless at the range in normal daylight, I can see some utility on a self-defense gun in very poor light, but they are just too hard to see for general use under any normal recreational shooting lighting situation.
As to scopes or red dot sights, for me its a no brainer, red dots rule for speed, scopes rule if your game is trying to shoot them all thur the same hole.
I'd suggest getting a cheap scope and a cheap red dot sight from CDNN and seeing what suits your shooting best. My first red dot was the Tasco Pro point and while its still on the Neos and works great, the cheap ones at about half the price work just as well for me. I made the mistake of starting out with a rather expensive Leupold scope and since I quickly discovered that I don't really like using scopes on a handgun, its been pretty much a waste for me. YMMV.
Nice thing about the Neos rail is that you've lots of mounting postions to get the overall balance "right".
