This I can tell you the LG is actually one generation earlier, and the Samsung you look at is the current generation, the LG equivalent is PY5D. If this suffices to help you to make a decision. And, LG screens have more problems.
See if you can transfer the credit to a LG HTIB, or perhaps the dual format Blu-Ray HDDVD player. LG "hardware" is not bad. IMO, even to forgo the LG credit is worth it.
