Checked with a few stores and evidently Marineland does not sell the corner overflows any longer - found an intact corner overflow in a "used" section of one store here in Montreal that looks brand new for $10! I've scoured the internet with no luck - so still looking for another one - if anyone sees one - please let me know - I am back in the Dayton area for work every other week now....
Thanks...

PS. Was great seeing everyone at the swap this weekend - just sad that I couldn't buy anything.... just visited Raging Reef here in mOntreal - only 5 min from my house - they have some SWEET Stuff.... can't wait to post up my new build as I get settled into the Montreal area...
