Pleco Identification (56K Warning)

I do believe it is Hypostomus Plecostomus or Pterygoplichthys Scrophus with my belief leaning towards Hypostomus Plecostomus. I check my pleco and there are no spikes - it was just a phenomena of the picture that made it look like it had spikes.

Thanks for all the help and info!!

I went to the LFS (petsolutions.com local store) and they refunded me my money according to a common pleco with no hassles at all.

Thanks again for the help!!
 
He looks like my common plec.
