AG-HMC40 vs. AG-HMC150 which is better?

I just got the Canon T2i as well, and I am loving every second I shoot with it!!! No more crappy HDV compression, no more converting 1440x1080 to 1920x1080, better lenses, better low-light, AND, I upgraded from my old HDV setup without spending any extra money (I actually had $100 left over!). Thank you super-cheap-but-high-quality technology for pushing the lever of excellence a notch higher once again.

good choice! Have fun with it sir

Just a quick note: when taking photos, keep in mind that the screen shows about 2 stops above what the light really is. I would recommend doing some test shots - particularly in low light situations to see the impact or difference.

I have this same issue with my Mark II!!! DRIVE ME NUTS! I actually just started using the histogram for everything now, or turn on highlights and take a still and find out where you are overexposing in the whites and dial it back about 2 stops. (very scene dependent)
