I am trying to build my own cheap and easy gb trap, for the fact I’ve never actually built anything before, could someone please give me some pointers or sumthing thanks.
The absolutely easiest would be a repainted RGB Ghost Trap, the only thing it needs is repainting (and a replacing/recovering of the tubing), for an example check here
it is based on the cartoon obviously so it is not 100% movie accurate but close
prototype7 has a trap he is building from found parts at places like Wal-Mart, he said he spent around $10 so far, AFAIK he has not finished yet, thread is here

Hey thanks for the mention Drakk…
Sam- you should definately check out my thread. It’s not movie accurate that’s for sure. It’s a custom design made from found parts and local stores. The bare minimum could be built for about 10 dollars in parts. I’m going to spend more along the lines of 20 on mine because I want lights in it but my thread is a work in progress sort of thing. Feel free to follow along! 
he’s right this is the best “cheap trap” ever, but if you really need to go “ghetto” just use a wooden block with stuff glued or drilled onto it. that was my first sad trap, but i was happy at the time
Hey Ectoneon,
There is always a use for the ‘ghetto’ traps. You can decorate the inside of the Ectomobile with them and carry the ‘hero’ traps on your belt.
Most people aren’t really going to know the difference, except one lights up and one doesn’t.
Hope this helps,
