Here's a pretty comprehensive gallery of glitch VST plugins in nearly random order.
dblue Glitch combines a lot of the known good glitch effects under one roof. http://illformed.org/glitch/
arcDev noise industries http://device.antisound.net/ has Blittr and Hosebeast for buffer-sampling stuttery gl*tch box with a nice x-y pad & useless-but-cool wave and multicrapfx shredder.
ndc Plugs http://www.niallmoody.com/ndcplugs/ has several great glitchers like Buffer Synth (several great variations of stuttery and repeaters), Reversinator, Stretch & Squash, The Modulator 2, Tempo Sync Reverser and more. The names somewhat explain themselves.
Smartelectronix Koen Tanghe http://www.smartelectronix.com/~koen/ has KTgranulator that pays homage to the granular blocks in audiomulch.
Smartelectronix Destroy FX http://destroyfx.smartelectronix.com/ has, for example, the stutter/repeater effect buffer override, zipping and sliding thru time with scrubby and the modulator Skidder

Smartelectronix mdsp http://mdsp.smartelectronix.com/2005/07 ... review.php LiveCut is still in development but works like a charm for all manner of slicing.
Smartelectronix Bram http://bram.smartelectronix.com/ has Supatrigga for slicing and MadShifta for pitching and feedback effects. Bouncy does the bouncing ball delay.
Daisypusher is a "beginners glitch plug", available at http://www.kvraudio.com/forum/viewtopic.php?p=1632468
