Which Stepping/Date of 2100 should i get?

I am getting a new chip and was going to get barton, but @ $150 for 2500+ (and it won't be out until the end of feb) i can't get it. so i will get a 2100+ tbred b instead. i have searched this forums and was wondering which stepping is the best to get? as far as i can tell 0249 is the best (i can only go up to 1.75vcore because i am using kt3 ultra 2). which stepping should i get? and if possible the place to get them from.

TIA

0249 and 0250 are both good, and some are having great result from 0302. Try to locate the exact stepping at Excaliberpc

0245 AIUGB is another great one

2100 AIUHB 0302 here and am at 2406mhz burning in to go higher.
