i am in the exact same boat as the thread starter, 15,no job, no money.
i did a custom fab for a center skid that also covered the steering servo. it looked good when it was new but rocks put a ton dimples and scratches on aluminum.. i also made a roll bar for my maxx but took it off in favor of an ebay special full cage.
custom fabs are the way to go for a genuine "custom" look (i hate when people say they have a "custom ride" when u bought all the parts simply bolted them togher)
BTW metal skids are just for the look of metal under there, plastic is the advantage IMO because the can flex and give a little when u slam into the mailbox or whatever, metal just bends and u only have a chance at bending it back out properly, otherwise ur just out like 20$ for a peice of metal, besides they only lookgood when they are new, if u going for the shinny new look , just replace the stock skidplates when they get to scratched up.(personally, trucks are ment to be used not showcased on a shelf...)'
but keep up the homemade stuff guys!
just my .02
