majesty88, I bought exactly the machine you are talking about. E-Machine is owned by Gateway which in turn is owned by Acer. I was apprehensive at first but have been pleasantly surprised.
I tried Toshiba, Compaq and Acer brands before getting this one. $ for $, this is the best deal I have found and stands up to the three brands I mentioned above.
It is too soon to know how long it will last for me, but my search found eMachine desktops holding up great.
