Alright my anime recommendations are Full Metal Panic because that show was bloody hilarious
and had a good serious story as well The new Fullmetal Alchemist Brotherhood if you liked Fullmetal Alchemist the original then Brotherhood is a hundred times better because Brotherhood actually follows the Manga Storyline unlike the original that started out following then went three sheets to the wind... If you like Mech anime then I would also definitely recommend Macross Frontier a very good addition to the anime Series as well as the OVA Series for Macross Plus was really good if short.... There is also Black Lagoon a great Story bout mercenaries I think or maybe they were Pirateish also you may want to check out One Piece in the original japanese form was hella good and will keep you busy with almost 500 episodes Darker then black I have recently gotten into was pretty decent show of course Naruto up to I think the first 140 episodes were good and then I would recommend just watching Naruto shippuden because believe me after the first 140 episodes of the original Naruto it turns into filler garbage ummm another really decent show is Katekyo Hitman Reborn... Rosairo + Vampire in both seasons was actually a pretty fun and different Harem show.... Line barrels of Iron was also a really good Mech show.... Ummm Eyeshield 21 was actually a really fun Football show which surprised me because I normally hate Anime based off of sports also if you like Dragonball z fighting kind shows then check out Kenichi worlds strongest Disciple Well I can keep going on and on (I have nothing better to do at work and I have already exhausted most of Western TV) but that list there alone should keep you going for a good couple of months and thats watching anime pretty solid everyday
I will also bring up Bleach because a lot people like Bleach but I hate it for the reason that several times Mid-arc they go into a completely different arc which pissed me right off but the show wasn't bad if you can stand that sort of thing also good places to watch anime are

edit: Also some one brought up Rave master Groove which was a really good show as well but it ends mid storyline which was a pain in the *** but for you who brought up rave master go check out Fairy Tail its made by the same guy who did Rave master
