Why did it take me so long to notice this thread... oh well, I guess late to the party is better than missing it altogether!
Some of my favorites...
LA 0
* anthropomorphic bat (savage species): size small. land speed 5, fly speed 20, +6 wis, -4 str, -2 cha (makes great druids, especially after lvl 5)
* dwarf (PHB): most powerful core race
* elan (XPH): abusable expanded race
* faen (Monte's Arcana Unearthed/Evolved): simply an awesome race. I've adapted it to be my homebrew's "elf". Faen-sprites are great casters.
* warforged (ECS): most powerful expanded race
LA 1
* dark creature (Tome of Magic): hide in plain sight, who cares if you get anything else (and you do)?
* draconic creature: half dragon lite. Not too shabby.
* feral (savage species): decent for the cost, increasingly awesome if you have non-class HD.
* half-ogre (dragon mag): stupidly powerful. +4 str (I don't remember what else atm) and you get all the mods of a size increase (med to large nets you a +12 str, etc)
* half-ogre (savage species): a solid race for LA 1.
* mineral warrior (underdark): ridiculously good. DR 8/adamantine, and other lesser things
LA 2
* grave-touched ghoul (libris mortis, book of bad latin): str +2, dex +4, int +2, wis +4, cha +2, claws, bite, paralysis... whats not to like? Oh right, that whole "evil, gotta eat people" thing.
* half-celestial (exalted deeds): if you knock off all of the HD-requirement abilities, its LA 2. BoED says so.
* half-dragon (savage species): This version of 1/2 dragon doesn't get the BW or energy immunity. I call it "lesser half-dragon".
* phrenic (XPH): very nice package of psionic SLAs. +2 int, +2 wis, +4 cha.
* saint (BoED): benchmark LA 2.
* shadow creature (Lords of Madness): stronger version of Dark. You're always in stealth mode as long as you're not in daylight.
* winged (savage species): perfect maneuverablity if you manage to have a 17+ dex (considering it gives you a +4, this is almost a sure thing)
