The last artificial tree we had lasted almost 15 years until we outgrew it; I bought it at Target in 2005.
This is very similar to our current tree, which is only about 3 or 4 years old; we can choose steady or blinking lights, clear or multicolored. (DD and I prefer multicolor; DH prefers clear.)
I kind of miss stringing lights, though. I picked up the task when I was a high schooler & my mom had moved out.
