Really good/Essential outboard gear.

Hey folks.

Sorry i've not said much over the past week. Had ALOT of work on with Christmas close.

I'm currently working on finishing up my guide (http://www.forum-mixingtips.org/before-you-record-f3/a-guide-for-beginners-t136.htm), and I was wondering if anyone here has any suggetions on any piece of gear that would be considered essential/extremely good IF someone was wanting to add some outboard to their home studio setup that they have been so patiently crafting.

The last section I'm working on is outboard gear and i plan to discuss exactly what outboard gear is, and why its so valuable, and was wondering if you had any suggestions on what peices of gear be considered usefull in a home studio.

Thanks in advance. Greers7j.
