Cheaper is always better when it is the exact same GM part #.
Try Patrick @ GM parts house. He is a forum sponsor
and I am betting that he will price match GMPARTSEAST. Do not PM him, send him an email. He will probably send you back a PayPal link to do a quick purchase. I have done this many times and he is an excellent seller.
His email is firstname.lastname@example.org
