id buy a stainless rollcab from one of the mobs on ebay or suchlike , a 3rd of the price and much more durable than the equivalent snap on mac etc , fill it with decent quality stuff like teng, britool, taskmaster, halfords pro spanners etc, i wouldnt go for 1 big kit from one mob as lots of stuff in these kits you wont use,plus lots of it is poor quality, its horses for courses so id get the basics and leave room for the more specialized tools you will need to do a job like this right.
