Not at all offensive. There's zero harm in asking.
And 100% if revenue was my goal I'd part everything out. I was just trying to explain why I need it to be an all or nothing proposition. As much for the benefit of anyone else that reads this as yourself!
If I can't sell the setup for a reasonable price in its entirety I'll move it with me. I just don't want to be stuck selling my favourite things (like the foxface

) and then being stuck having to move the tank anyways.
Cheers,
