I paid $975 for mine new in 2008 which at the time was a pretty good deal. Still sucks to see it going for so much less especially after hearing about how well L's hold their value. Oh well, I guess its better than electronics that are obsolete and nearly worthless less after 3 years. At least I wised up and stared buying everything used that I can.
I'd like to sell it for the 24-70 f/2.8 II, mainly for the brighter viewfinder and better AF in low light. But heck, as cheap as the 24-105's are going, its almost worth keeping it even if I get the new one since the IS can come in handy at times.
I see people pay msrp for a 70-200mk2 (2500 plus tax) only later to sell it a year down the road for 1900....
and now you can buy a new one for 1900.
