Yes but this is more for the people who are looking to buy exp so they can figure out how much they need, and how much it is going to cost them in total.
Also put the enchantments for a diamond tool when enchanted ex lbl 1 exp lvl can do eff 1 unbreak ing 1
Instead of doing that, i'll just leave the link of an enchantment simulator that shows everything you would want to know about what enchants you can get, and the percent chance of getting them.
http://radthorne.com/exp.php I wrote this exp calculator, it's useful for levels greater than level 50. It also shows how many mobs you have to kill to get to that level.
if you have an iOS device (iPod Touch, iPhone, iPad) there is an app called iEnchant. it costs $0.99 to buy it, and it can be helpful. Someone I know has it, I won't mention his name so he doesn't get bugged, and whenever I enchant things, I know what to expect. It really is great, I wish I could get it but I have to update my iPod Touch...
