This is a very cheap but complete set.. some of the stuff might break, and some of it might suck, but at least you're completely set up with everything to start for $33, you can decide if you like working on bikes http://www.amazon.com/Brand-Home-Mec...ef=pd_sbs_sg_3
I'm leaning towards getting the SK-1 and just adding stuff as I need it. A lot of people will give you the advice of just buy tools as you need them, and to not buy cheap tools because you just end up buying them twice (buying quality later).
After looking at that kit I forgot to mention you need a chainwhip too.
Those kits are nice; I have a full set of tools from my automotive days, so I only really needed the specialty items. If you're lacking in basic screwdrivers, etc, you may want to go the route of that kit.
I like to buy on an as needed basis bc I know that there's not going to be a dollar spent on an unneeded tool. You can usually get away with the laser cut park stuff for about $15 or less per tool.
Sometimes there will be tools that you need to use maybe once a year at most (crank puller for example). In those situations I compare the cost of the tool, to the cost of the shop charges to spend 5 minutes to do it.
