Why can't you wait until October 16 announcement? If new iPads are announced that day, your options become so much wider. At the least, if you still want an older iPad you might be able to go out that day and grab a firesale iPad3 or 1st-gen rMini since the vendors may be unloading them at steep discounts.
Wait a few more days, I say.
iPad 2 just doesn't cut it any more. The outdated CPU/hardware performance and the terrible camera (altho that may not be important for your iPad use). Remember it has that legacy 32-pin port, not the newer Lightning. I could list a couple more things lacking about iPad2, but I say
. just wait until Oct 16
