Skimmer selection

[Treebeard]

I am considering upgrading my in-sump skimmer for my 90 gallon tank. I currently have a Euroreef RS80 which is on the small size for this tank, and was thinking of getting a larger Euroreef because the RS80 has been great. Only problem is, I do not see any Euroreefs for sale on any of the online Canadian sites (not sure about the LFS).

Does anybody have any recommendations for skimmers comparable to the Euroreefs, preferably under $500?
