Maybe you should give a try with mathematica, the function is BellB[n] It is much faster than maple.
bell(1000) takes forever to compute and almost instantly with mathematica.
Jack Schmidt just wrote on the sage-devel mailing list that GAP takes under a second to compute Bell(1000) - that means that SAGE would also compute it under a second because it uses GAP's Bell,

Hmmm. John Cannon reported that his 2.4GHz Opteron took 0.9 sec to find B(2999) using the Magma transcription of my implementation. At a rough guess, this would scale down at most 0.05 sec for B(1000) ... WFL
