Buying an iPad differs from people to people, so your requirement was due to the utility it had in controlling the system. Some buy it for browsing and some for games etc.
On Topic, Its a good buy provided the ipad 2 is in good physical condition.
Off Topic, And if someone plans to buy new iPad 2 16GB(24,500/-), then for extra 6k they will get the new iPad (or iPad 3 for 30,500/-)with Retina Display- 4 times better display quality than the iPad 2 and much better than the HDTV display quality) with 5 MP camera and 1080P video recording, Quad core graphics processor is simply the best deal.
