Hi everybody!

I need a Texas Instruments TI-83 Plus Graphing Calculator for use in school. I have a couple questions about these, so anybody who is knowlegdeable on this topic, please help. I am not looking to buy one from AMDForums, so that is why this is not in the 'Hot Deals' forum.

1) What is the difference between the TI-83 Plus and the TI-83 Plus Silver? I have seen that the Silver editions are higher priced than the regular edition.

2) In stores, these calculators are about $100 each. Do you now of any places online where I can get them for cheap? They must be new, in a retail box.

Any help would be appreciated. Thanks in advance!
