I am building a rail gun and i need capacitors, but i only have $40 max?

i would not prefer to buy them off ebay, any ideas, like buying from a company or something, caps have to be udleast 400v, and i prefer electrolyc capacitors

Answer:
With only $40 you are not "building". You are instead only "dreaming of building."

No matter how cheap you get them $40 won't cover it. Beside if they are coming from ebBay or someone's old salvage they may have deteriorated severely in capacitance.
ebay or try a local surplus electronic store or start pulling them from old electronics.
