Following are pictures I found on the web. Now, the costumes that look exactly like the ones on the show are made by fans, from actual molds, they make the helmets, costumes run around $300 to $600 dollars. The inaccurate looking ones of course are cheaper. Now, there are certain costumes that don't look accurate and are made by fans, like Zedd, Rita, Megazords, Kegaleshia, etc. In japan, the regular uniforms (Jackets, etc.) are available for sale for adults. Saban should really license the suits, he would make a lot of money, like the Star Wars people do.
