If it's just straight letters you are after then the list only comprises 676 possibilities.
I've got five (only one of which I would sell 'BL'), you already know about 'LL', so you've already got that down to just 670 left.
Of those 670, there are among their number another 385 that are available to register at ENOM right now (although all have quite high premium prices), so you only have a range of 285 possibilities.
With a number as low as this I would suggest your best way to reach a good deal with people on a two-letter is to e-mail the individuals who own them directly (most are actually in the hands of just a few people as some own well into the double figures).
Who knows, you could be lucky and get a two-letter with a $500 or less premium.
If geos are hot - then I would suggest that two-letters are somewhat 'hotter'. Good luck with the search.
