Protein Skimmer for a 300 gallon FOWLR

[Hustler]

Im in the exact same boat.... 300g with a 100g sump and I dont want a BK its just too fancy
Im knee deep in research for an affordable plug and play (seen the becketts but couldnt build one) skimmer that is double the ratings but still not over a grand....
So far the ASM G4+ but maybe 2 of em.... the skimz large one or the INS400 by reef dynamics I actually talked to the owner for a half hour today after seeing his half hour demo youtube video with LAFishguy.
I cant find anything huge and used..... Ebay is nothing but made in china knockoffs and really everyone just pushes the big brands so Im still digging....
Please pm me when you get narrowed down as im in the same boat
