Canon lens choice? Effective 300mm?
Eventually, I would like to upgrade to a Canon EF 70-200mm f/4 L IS USM. But for right now, I am doing a little bit of everything...low light, action shots, portraits.....etc (horses). The following lenses are what I have been looking at, however I am open to any referrals/suggestions that you might think would work better in my situation.
Canon EF 70-300mm f/4-5.6 IS USM
Canon EF 75-300mm f/4-5.6 III USM
Thanks 
Considering that the price of the 70-300mm IS nearly gets you to the non-IS 70-200mm f/4, I would keep saving to at least get the non-IS model. Then you need to decide if you should keep saving until you have enough for the IS model. This will be a lens that you will likely own for decades and use a lot, so the extra bucks for IS is probably worth it.
While you're saving up, consider renting one to give it a try. A Yahoo search for "lens rentals" will find several online companies who will rent lenses to you through the mail.
