commercially available cDNA constructs - feeling lazy and don't want to make them. (Oct/19/2010 )

Hi,
I was wondering if anyone knew of a commercially available system where I could purchase constructs of cDNAs of my choice.
I can't find the human versions I need in any papers (so I can't write to the authors and beg for a sample), and the time it wold take to make them seems unreasonable.

wow, just found one... $500 per plasmid .... Ok, i'll have to see if someone has human versions.
