Need a new skimmer

[Lance]

Hi everyone. I need a better skimmer and am looking for feedback from members that are familiar with these brands. I am interested in the Tunze DOC-9010, Deltec MC500 or Aqua C EV180. Info I've read on these skimmers shows that they are all pretty good, and they fit the skimmer chamber of my sump. Can anyone familiar with these models give me the low down on them: such as performance, setting, ease of cleaning, etc.

90 gal corner bowfront, 50 gal sump, mostly softies & LPS with a few SPS (more to come) 8small to med fish, 2 shrimp, hermits & snails. Tank has been running for almost 4 months. Parameters are all pretty good.

PS: I would consider buying used if in good shape and willing to ship. I have family in Surrey and Calgary who could pick it up as well. Appreciate any help you can give me.
