What to use for trim molding???

OK, I am going bananas trying to figure it out what to use,,,
aluminum, vinyl etc.. everything is so freaking expensive!!
what other and cheaper options are there to protect the edge on my TD??
my budget is max about $80.00 but some companies charges half of that just on shipping...
any ideas?
Thanks in advance.
