Excellent advice, though for someone like Barry without a single tool there are advantages to getting a tailored set. Here in CHina, SATA has a couple of automotive sets that cover a lot of ground with a lot of quality for a decent price. The
basic kit shown here can be had for a bit north of 500 RMB. Excellent sockets, box wrenches, pliers, screwdrivers with full range of bits including Torx and even two spark plug sockets. And a box to keep it all under control for those of us without a garage...
Here's that kit in
Taobao for under 500 rmb.
Beware: There are lots of really crappy and counterfeit tools in China. You get what you pay for.
cheers
