you can get red like mine and green from fleabay, the seller (i forgot) also makes blue visors for the imperial guard, he may make a blue t-visor but I cant say for sure since I am not him
You can also use a motorcycle visor and cut it out, they come in iridium, fun stuff
BM and Fett Pride are both excellent, but if you dont want to spend over $250 for one, you can get one from SAZ, he's just starting to sell his buckets, like $150 or so plus shipping.
I used the priority envelope for my buckets.
As for trash can armor, it can be glassed, but I am using mine for fun, not fuction, so I dont need to glass it. Metal is nice, but heavy, and again I am making my armor for fun so no metal.
Oh yeah, I forgot about this guy:
Trash can armor how to video for newbies.
