Yea, it'd be really good to have both to expand your tonal range.. And just think, you can run one of the stereo channels into the NM (Short for Neo Mistress just incase you're not in with the lingo) for more brain melting tone awesomeness.

Both are nice, and youl have to determine what your going to need.
But don't forget to take a look at the MXR range's flangers, IMO there some of the nicest flangers out there, especially the 117(someone was selling one for about R600 in the classifieds, its a steal), but its little brother is also a really cool pedal... ?
