Edgestar, Avanti, Vinotemp

Ended up ordering the Avanti. Got a good deal at wal-mart.com. Now what??? I want drawers but have to wait to measure the unit. Is the Oasis overkill?? I dont mind spending the $100 if it makes life easier and a stable humidity. I also like the fact that i can add fans and control them right through the oasis unit.. Do u still use beads with Oasis unit?? Thanks again
