The only comparable alternative I can think of is Ashton Heritage Puro Sol, which unfortunately costs about the same as the DC and -- surprise -- is made by Fuente. You could also try any of the Cameroon wrapped cigars in the regular Fuente line, but they're not like DC.
Here are three longshots:
Oliva Serie G, which also has a Cameroon wrapper and has similar body if not flavor. About $3-$5 and a great cigar in its own right.
The now-discontinued Peterson line. About $60 a box at Holt's and very good for the money.
