Paladin:
Baton of Faith (2HB that's damn-near BIS until FA turn-in) (L20-46) ~100-200p
Also the Sword of Skyfire you have for SK should be listed for PAL.
Enchanter is about stacking CHA ASAP:
Crude Stein -15CHA, 50p
Golden Cat Eye Bracelet - 7CHA, 35p
Gypsy Medallion or Cat Eye Plat Neck (JC) - 9CHA, ~150-200p
Electrum Star Ruby Ring - 7CHA, 100p
Platinum Star Ruby Veil - 9CHA, 250p
That's 61 CHA for 770p, putting you over 150CHA for even the lowest CHA enchanters (assuming +25CHA on creation). Although an extremely strong case can be made to swap the two CHA rings (14CHA/200p) for two 5AC/55HP (total: 10AC/110HP) rings for 500p. Being able to charm reliably from L12 is game-changing.
Bard:
Sarnak Emblazened Tabard ~100p -1AC from Banded, but you'll use the MR for a LONG time, plus 10HPs at low levels.
Beartooth Necklace - 50p.
That should eat up the rest of your budget, unless you are saving that for songs (Since bards only get 1 song per level, their budget for spells is much smaller).
