I could see you spending a little more money on the 8.8, but I wouldn't justify it myself. Definitely not the 30 though. If I were you, I'd lunchbox'm and be done with it.
The 8.8 has an extremely weak carrier. I recommend a detroit or selectable. The aussie D30 works great but, spring for the hardened pin and check you carrier every 6mos or so for wear.
