from my 1 year of experience, start from the basics. and you can go anywhere you want with that.
i started out with Born to perform and one sankey's anytime anywhere. Oz's Born To Perform taught me all the basics and the routines that i use all the time. and sankey's works are also very good because he teaches the some of the slights in the dvds.
i later bought bobo's coin book and royal road to card magic and mark wilsons's book (and haven't really looked at those alot...) for references that i might use later on.
from there, i was able to go into XCM, coin magic, card magic, mentalism, and alot of fun little tricks (self tying shoelace, stigmata, greed, etc)
i made the mistake with buying alot of effects when i first started (OMG CUPS

) and i dont even use 2/3 of them on a regular basis
luckly i found this forum and saved my self alot of money and learned alot of things, well that was my rant
