HOB Skimmer Thoughts?

[rums]

Howdy,

I was looking for a (cheap) HOB skimmer and came across this on eBay. Anyone have any thoughts?

It also goes by the name KNOP or Excalibur skimmer, as seen here:

Does anyone have any experience or comments about this thing? Price seems quite reasonable if it's even half-decent.

Thanks!
Rums.
