The one thing I need?

[davekershaw]

Just wondering, if I list my gear, whether there is one thing that anyone would add, that I am really missing, to improve my production.I'm still learning, with the gear I've got, so maybe I already have enough, and it's just down to improving my skills.Still trying to get my head around compression and limiting.Anyway, here's the list:XP3 x 325 gig hard drives 1 x 250 gig external hard drive for backupsDVD BurnerSonar 7 ProducerPresonus FireboxTapco S-5 monitorsSennheiser HD 201 headphones(yeah, I know they're cheap.just to get me started)AT2020MK-012Roland 180 midi controllerAxon 50 guitar midi controllerColossusEWQL GoldGuitar RigOzoneAre there one, or two items, maybe hardware, I should really have.Thanks in advance.
