i would say Avenue- it looks like Dhorian has some good stuff in it- besides, it'll tend to suit MY style since im influenced by the buck twins (and they helped make Avenue)
I emphasise on MY style. that doesnt mean it will suit you immediately, however i own DGP 1-3 and i only found some things useful there, not too keen on things such as JoeBlow and that window trick (forgot what its called)
But nacho mama's triumph and Ego Force/Ego Change is definitely worth its money. =]
Cant really say anything about avenue- though if i had the choice right now i'd buy the DVD-cept im lacking funds!
Edit:
Damn, a DG hater. what's the world going to. =/ that's like saying you hate santa clause. not implying DG's fat, but like everyone likes santa clause- which means everyone loves DG!
I think Mr.Bayme and DG should have a joint project, that'd be hillarious. Bayme is funny =D
