Doesn't this seem to cheap?

I would be hesitant as well. The resealing is fine as long as it's well done, but WHY was it resealed? Is it old? Lots of scratches? The RedSea protein skimmer probably the Prizm Pro and would then be worthless imo, and looks good in the trash. If it's the Berlin, then it's ok. The light may or may not be decent as well, depends on brand and reflectors. Probably needs a new bulb too.
