Which Grading Company to Choose at this weekend's National?

I plan on attending this weekend's National in Atlantic City. PSA, BGS and
SCD Authentic will all be offering on-site grading. I have had a few cards
graded by PSA in the past and was relatively happy with the results.
Recently I have been hearing about BGS and SCD Authentic and now I am
wondering if I should go with one of them or stick with PSA.

The cards I am thinking about submitting for grading are not vintage cards.
They are relative new releases.

Any suggestions or comments would be greatly appreciated. Feel free to reply
to this news posting because others may be wondering the same thing. You can
also email me directly. Just remove the nospam from my reply to address.

Thanks for reading.
