MarkieeMachete, I would suggest you try out:
early Stan Lee/Steve Ditko Amazing Spider-man if you're interested in the character's beginnings (example: Amazing Spider-man Marvel Masterworks trade paperbacks)
Ultimate Spider-man by Brian Michael Bendis/Mark Bagley for an alternate and modern take on Spider-man (example: Ultimate Spider-man Ultimate Collection)
Amazing Spider-man by J. Michael Straczynski/John Romita Jr, for a more recent Spider-man (example: Amazing Spider-man by JMS Ultimate Collections)
Amazing Spider-man by Dan Slott/Humberto Ramos for a very recent, up-to-date Spider-man (example: Spider-man: Big Time Volume 1)
There are many, many other great Spider-man stories, but these are a few that may whet your appetite.
