HD33 Glasses very quick question

Hey everyone, I ordered my HD33 today Im pretty excited to finally get my theater done. My question is if I get DLP link glasses do I need another emitter than the one sent with the HD33? I know the one incldued with the projector is for RF glasses so do I need another if I get DLP glasses? Also what other glasses other than the optoma ones can I but to use the RF emitter? Also can I use RF and DLP link glasses at the same time? Thanks.
