I recommend watch Ebay. Ebay seller have some nice boxes for about 50-60% of new.
I bought my KRL1032 only about year old for 4500 in 2007 from Ebay.
So this maybe out of your price range but you can save a lot buying used.
buy a box with large draws is better than a box with a lot of small draws.
When buying on ebay : setup ebay and paypal account in advance. Use paypal to pay for the box.(warranty)
pickup trunk and low bottom trailer with a long tailgate is likely the cheapest easies way to move it.
buy close to home no more than a 1 day round trip.
