Please suggest Samsung Galasy S2 i9100 alternate

[scott1391990 2]

Can you guys suggest some alternate for SGS 2 I9100 under 13k in terms of performance and camera quality.
Hows the Samsung Galaxy S2 Epic 4G in camera quality and performance when compared to I9100? Do they share same hardware beneath them except for the bigger screen in Epic and CDMA support?
Do tell me if there is any other difference in them.
And also, suggest any other alternate phone to SGS2 I9100 with same camera performance.
Have looked at Atrix 2 and Droid Razr under 13k but their camera isnt near to that of I9100
I have never used CDMA so also tell, if it makes any difference whether you use GSM or CDMA?
