i would suggest you to buy what you can afford......
snap on is pricy but remember snap on truck come to you at your work... also snap on tools work good and designed to be flank to make bots or nut to not be rounded...snap on is little over-engineering but it is great tools and i had no problems... i did not break anything but i did accident to overload on my 1/4dr ratchet and already on second rebuilt...
craftsman tools are great for everyone but everyone have their preference as some person dont like feel of ratchet or handle...
it is their choice and it is your choice too!!!
i own craftsman, snap on, matco tools, and matco tools... i do own proto and cornwell as same with William (divison of snap on)... all is different feel and style but all tools are do same thing to work....
you could get lot and lot of craftsman tools like this site... for like 7,000 dollars then you had all and maybe dont need buy more tools but need impact swivel sockets...

or you can more tools but pay lot and lot of money for snap on tools 2,331 dollars for that set (it seem small than craftsman's)

well it is vary by everyone!!! i just graduated from Ivy Tech last May 2007 but had over 20,000 dollars investment in tools and snap on boxes(i paid my snap on boxes as used (KR1200 for 1,200 dollars and KRL1001 for 2,500 dollars plus my other toolboxes to trade in from my snap on guy)
i am still buy the tools to do job easier for myself as use brain and dont overload myself or i would get hurt myself...
i would recommend you to get knee pads so you will not get knee hurt from kneel on shop floor... many technician work with me that they hate to kneel on shop floor...
