Well I was hoping to get a few more opinions on this but I guess since they only made like 300,000 fieros (wiki), experiences probably would be limited. I was hoping to do this on el cheap side. $25 beats $200 and I kinda dig doing mods that are "custom". Since they have plastic tanks like you said and go bad, I guess I'll stay away from this one.
If all the extra parts are connected to a main part that I want, then I'm technically just buying the main part and the extras (since connected to it) are part of that part.......right?
