The package is a decent deal.
The atman pumps are not very energy efficient.
But your mind is in the right area.
I purchased the BM180 EX which was the largest skimmer that this particular eBay vendor had about 8 months ago.
Skimmer body rated up to 400 gallons. Cone body with cup roughly 11.05"x9.05"x25.40".
I offered $210 and they accepted. (Free shipping/no sales tax) I ended selling the pump that came with it for $20.
Note the skimmer originally was an internal pump design.
After much research as to how the ITech series skimmer were so successful I noticed they utilized the Tunze Hydrofoamer. Energy efficient strong air turbulent specs.
I picked up a used 9430.04 Hydrofoamer supposedly rated up to 792 gallons. (Tunze claims)
I scavenged all the original parts from the eBay package plus some PVC fittings at Home Depot.
I had much more success implementing the bubble diffuser to keep rock solid tuning stability.
I modded everything together, pump is on the exterior and now I have an ITech like inspired creation. Well suited for my bare bottom total 340 gallon water volume zoa/LPS system.
Total investment $290.
Pulls extremely well and dead silent!
The only way this would be a better designed skimmer would be if I had a slightly larger skimmer body so I could crank up the tunze pump a little more. 8 inch body expanded to a 10 inch body would be nice. Or if I had the room a way to expand the neck another 3 - 5 inches. Larger the reaction chamber, the more effective your skimmer will be.
The BM skimmer body quality is so so. The acrylic is not super thick,but if you don't drop the skimmer and crack it, than this doesn't effect anything mechanically speaking.
Makes you think how much marginal profit space skimmers have. This forum offers really nice wisdom sharing threads. You just have to read through all the opinions to collectively create an original cost effective idea.
The reason I was going to sell this skimmer was because it developed a small hum and I didn't know why. Turns out salt creep got into my air intake adjustment clogging the feed causing the pump to cavitate. Simply pour some hot RO water down the intake to clear the line. Back to awesome again, no more sound and stronger bubbie production!
There is a guy on the national form, JediMasterBen selling a nwb-150 w/ Bubble blaster hy-2000 pump. I think this would a killer skimmer if you have the room in your sump. It's basically an SRO-2000.

Not sure how that pump is too big for that body. The sro-2000 uses the same body and pump, and that is the exact pump most people use as an upgrade from the otp-2000. I know the hy-3000 will turn it into a cannon. With that said, I've heard alot of great things about the G-4 skimmers.
