because of stupidity on my part i have to remake my character. is there a mod that has a merchant that sells all spells so i dont have to redo all the mages guild quests to rebuy my spells or look up all the form ids.

Nope, there's no such npc in the vanilla game or a mod that I know of.
One way is the console command psb but it should be used with caution as it adds all spells in the game (around 600). Filtering out what you require and deleting the rest could be more time consuming than hunting down the spells themselves.

Tamriel Travellers Merchants Wizard and Bard types all have different types of spells for sale those around Imperial Isle have the lowest lvl ones and those found out in wilderness have the high lvl spells up to journeyman..

That is my suggestion you could install that track down the wizard travellers and buy the spells and then dsable travellers if you like..

that might be more work than the mage guild quests. i use TIE so i already have TT in there.

i premake my high level character right of the bat cause i think levelling is stupid. i need the high level illusion and summons spells... im an assassin that sneaks in but im too lazy to actually do the killing so i have summons do it for me. that way i can relax and enjoy some skooma.

im pretty much done with them now anyways i was just hoping to avoid joining the mages guild since i want to play a pure character.

i heard psb console command causes game crashes so i avoided that one.

yeah that is quest in itself to track travellers down sometimes, unless you wait in rest spot for x amount of days..and wait for them in each region to come through..

TIE Travellers do have the spells for sale has well..

There is Leveller's shack by Willie Sea if you want to recreate your high level character, but you can't get spells from it. I suggest creating your own merchant NPC that sells spells and giving him the spells you want.

http://www.tesnexus.com/downloads/file.php?id=30962 is a mod that adds a vendor outside the gates of the Arcane University. He gives you access to the spell making and enchanting menus, cant remember if he sells stock spells though.

NPC in http://planetelderscrolls.gamespy.com/View.php?view=OblivionMods.Detail&id=2114 sells most of stock spells, though it edits some vanilla chests as well.
