Right, well, if you want something like what I've got for the house it will do most jobs pretty well then I can recommend;
Kincrome metric only toolbox, has enough spanners,sockets, breaker bars and other goodies in it to do most jobs.
A deadblow hammer
Vernier
Micrometer
1/2 inch torque wrench beam type
1/4 inch torque wrench beam type
Small cordless impact driver
Fein Multimaster with a few metal blades (much more useful than a hacksaw)
A corded or cordless power drill
Assorted emry paper
A few different versions of loctite
A few different types of tape (duct tape, electrical tape, foam tape, duct tape)
A good multimeter
Some heat shrink
A soldering iron
feeler gauges
Some assorted custom built tools to do irritating jobs like fork seal drivers etc.
And that should see you through pretty much everything, the only thing I'm thinking about getting that I don't have is a bearing puller... but I've got one of them at the workshop so I don't really need it, it just makes a few jobs easier.
That will set you back somewhere around about $5k or so if you get good deals on everything but buy good equipment, ie mitotoyo verniers/micrometers etc, if you buy crap you could probably get it for a bit cheaper, but you'd have crap tools.
On the other hand the minimum you can get away with is;
A 3/8ths socket set
A few loose 1/2 inch sockets and a breaker bar (you don't need a 1/2 inch rachet)
A screwdriver set
A couple of good pairs of pliers and some side cutters.
A multimeter
Feeler gauges
Thats about $500 or less if you buy good tools, if you buy shit, then you could probably get them all for under $200, but again, why buy shit?
Some nice to haves that would go with that minimal tool kit might be;
A combination spanner set
A small electric rattle gun
Thats probably another $500 worth of stuff again if you buy cordless, maybe $300 if you buy corded
I'm sure I've left some things off all the lists, but thats what I can think of off the top of my head.
