Get the stl-v2. It is really the nicest XML based budget thrower out there.
But if throw is your thing maybe an 15 usd Jacob A60 from DX.com is a good buy also. I love mine so much I just ordered 3 more :-)
X8 beats c8 any day but compare to HD2010 non are match. I own X8 and HD2010
Does anyone have beam shots of an Stl v2 and a HD2010? I want to directly compare them.
