Have you looked at the Sealey stuff? I like them, especially for the money. Ive got this one on the way for 105 new off ebay! so my topbox will have something to sit on! although im sure you'd need something much bigger. http://www.toolstop.co.uk/sealey-ap0303b-rollcab-3-drawer-with-ball-bearing-runners-black-p7973 maybe this for you? http://cgi.ebay.co.uk/Sealey-Tools-...icle_Parts_Accessories_ET?hash=item35a3894414
