I think I love Portugal, if only I could understand your language more, like with easier spanish
Then:
go with ATK200
View attachment 310385
This one is the Soda Blue limited edition (like a Fenderish Lake Placid Blue) it's the same ordinary ash (very heavy) with maple neck and rosewood fingerboard as other ATK200
Unfortunately it's not the former Indo ATK310 with triplecoil pickup
It really was the closest to Sterlings you can get with a non MusicMan bass: it let you opt between serial, phantom coil and parallel configuration
Present MIC ATK200 sport Ibanez proprietary CAP double humbucker, so the selector can just dial in front/both/rear humbucker. Less versatility yet plenty of punch n'power:
you stay in your price range (mine was . 300,00) and don't mess with Sterling SUBs, which really aren't on par with Sterling Rays and just feel poor
I can talk of present ATKs for I have the three of them: chinese ATK200 I posted you, Indo ATK800 Premium and Nippo ATK1200 Prestige (they're lighter: select light ash body) with additional front Ibanez proprietary Arch humbucker and maple fingerboard.
Hardware varies: on ATK200 you got Wilkinson machineheads, on ATK800 Premium you got Hipshot light machinehads, on ATK1200 Prestige you got Gotoh precision Vintage machineheads.
Cheers,
