As Lee said, hauler bags try and find a used one, however I have recently moved away from the racing hauler bags altogether as they all have issues, some break their zips easily some break the handles easily, I have recently moved to Ogio 9800 rig bags(around £140), if you shop around they are only a few pounds more than most decent hauler bags but will last you a lot longer.
Tools wise you can buy multi drivers, so you just have 1 handle and just keep changing the tip to what you need, this is a little more time consuming but saves money in the begining.
You also don't have to keep up with the jones's and have all the race branded tools and bags. I know many people who have and still do use basic tools from general tool shops and Cheap bargain shops, depending on how much kit you want to carry there's lots of options in B&Q and other hardware places to use in place of a hauler bag, many people use the rolling tool boxes.
Its all down to how you want to go racing
The main point is to enjoy racing and that can't be done if you're going round the track worried about the bill at the end of the month
