Ok, I have a Mesa Boogie M-Pulse 600 head and I want to protect it to the highest possibility that I can. One thing that came to my mind was getting a shock case to help support it, as well as my furman power conditioner *soon to come.* I'm worried that later on the road I may want to add an fx unit to the rig. I have yet to play a real gig ... so I don't know if it would be smart for me to get a rack at this point in time. I'm guessing racks help you but I don't know from experience. The M-Pulse is 2u, the furman is 1u ... should I get a 4u or 6u rack? Why do you choose? I've been looking at these: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=23793&item=3738747194&rd=1 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=41409&item=3739065654&rd=1 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=41403&item=3738745608&rd=1 Is there another case company I should look at? I'm trying to keep everything under $90 including shipping. Thanks.
