I started out with a green dot/red laser combo - but at 50 yds couldn't get any kind of accurate shots with it... I ended up getting a 3-12x42 scope which now allows me to see what I'm shooting at 50 & 100 yds without a spotter scope (I didn't like using that spotter scope either).
Got this based off the reviews: VISM Micro Greendot Laser Sight w/ Integrated Red Laser VDGRLB FREE S&H VDGRLB. VISM Laser Sights.
Used twice, I'll probably list it for sale @ $45 shipped...

For inside 50 yds, I'm considering a green laser which is reportedly visible in direct daylight... we'll see!
