Reyland's box would cost me about $4500 CDN to get it to my front door. If I bought it here I'd pay about $2900 CDN. (the TK0600 which has the better gearing)

There is one for sale in the local craigslist for $2000. I could probably ask the same for the Cossie 2wd gearbox.

I could have a new one in my hands in a week, or used this afternoon. So - easy to come by in my books.
