Yeah, I've thought long and hard about other options, too--such as a Gear Vendors overdrive, a 4WD transfer case with the "transfer" part cut off

Thanks, hadn't see the Gear Vendors unit -reading their site and it seems pretty convincing. It's pricey but could be taken to your next car or sold after you're done with it. If you did a 4wd transfer case mod it would whine when in low, I think a lot of them are speed limited too (?).
