Wanting to Learn Spanish

[JustAGuy]

As the topic states, I would like to learn Spanish. It's a bit embarrassing for me since I'm a Canadian of Peruvian and Uruguayan descent, and only a pure English speaker. My entire family speaks Spanish, most of the time, and the older the relatives, the more they speak it. I can understand about 90% of what is said; occasionally there is a sentence, a colloquialism or a word that I've never heard before. In addition to my partial understanding, I have no confidence in my current understanding of Spanish to speak it. Verb conjugation seems to get me down.

It's like this with me with lots things. For example, when I was new at poker, I played and won, then lost, then won a bit, then lost a lot more. I had a feel for it, but didn't really know what I was doing. I would call when I should raise, fold when the odds say call, etc. Then, I chose to educate myself, and now I can hold my own on most any table around (casino or home-game. The no-limit games really hurt me, though).

The point is that I want to educate myself. Does anyone know a good "teach-yourself-Spanish" course or book I can purchase over the 'net? I have to rectify this pitiful situation regarding my linguistics. The thing is, according to my heritage and my place of residence, I should be fluent in three languages, English, French, and Spanish. As of right now, I can understand French and Spanish, but can only Speak and write in English. Despicable!
