Kalmus Classic Edition K 03101, Warner Bros. Publications, J.S. Bach, Six Partitas and Overture in the French Manner, Hans Bischoff, ed., 1882, for piano, ISBN 0-7692-8604-6
I find the print, paper, and binding satisfactory in this edition, and it was $10.95 in an ordinary music store a few years ago. This copy does not mention the BWV 826 number you mentioned, however.
You could Google it, or try http://sheetmusicplus.com
; there seem to be several other editions in print, and there certainly are a great many recorded performances.
Or could you be thinking of some other Bach Partita No. 2...?
