If your really concerned about corrosion then a marine cable is tinned and allot more resistant to corrosion than OFC..
This is true, but it takes away from the power handling of the cable, not so much in line but at connections. Without question, OFC is the way to go. Unless you spend tons of time in/on/around the coastline (which I know you don't), tinned marine cable is overkill. Tinned cable was originally used to prevent corrosion caused by the sulfur that used to be used in wire/cable insulation. This practice is mostly extinct, so tinned cable isn't really necessary. In an automotive application the benefit of tinned cable would be when being used in situations where you are going to be making multiple soldered connections (connecting LED leads, speaker wire connections etc) as it readily bonds to solder (mostly tin). In a power/grounding situation like you are planning, where mechanical (crimp/fastener) connections will be used, using OFC is a better option as you will be getting copper to copper connection and not have a metal with higher resistance (tin) sandwiched between your connectors and cable.
In addition, don't be fooled by some brands CCA (copper clad aluminum) cable which is aluminum cable with a thin coating of copper around it. These cables are a waste of your time and $$ as they can be up to 90% aluminum, compared to the 97%+ copper content of OFC
Make sure you are getting what you are paying for. If it's 1/0 and under $3.50/ft it's most likely CCA, not OFC, which is tough to get under $3.75/ft unless buying massive quantities.
A 1/0 run , depending on length of OFC will handle appx 300A
A similar run of 1/0 CCA will only handle 210-250A depending on copper content.

I'll have to look into this, but 7 bucks a foot.
I'm into it at about 5 bucks a foot.
You can get quality OFC cable from powerwerx. ( http://www.powerwerx.com/wire-cable/welding-cable.html )
the sell highly flexible 30gauge strand size cable at more than reasonable prices
you can get 50ft. rolls of 1/0 for under $200 (<$4.00/ft)
They also sell their surplus and roll ends on ebay, just search for the seller "acdcelectricparts" sometime you can get 2 ga, 1/0, or 2/0 odd lengths and roll ends around the $2.00/ ft range
I have gotten some smoking deals from them. They are one of my followed sellers on ebay.
I know you have not seen the electrical system in my Av since I finished it in August, but all my cable in this Av, my last Av, my Silverado, and My subaru has come from Powerwerx/acdcelectric.
Here is one of their clearance items up right now. 15ft. of 1/0 OFC w/ red jacket and 15ft.of OFC w/ Black jacket for $65.00. That's only $2.17/ft.
