Just a heads up based on my experiences. Ive sold many tanks here, none of which I have been able to sell as comeplte set ups. Everytime Ive had to part them out. It does take a little longer, but in the end Ive been able to re-coup more cash by parting out as well.
Just my cents, you may have more luck parting it out, not everyone needs a complete set up, but every one needs parts and pieces at some point or another.
