If you want to save some cash down the road, take a look at a good modeling amp. While a basic amp is great for awhile, you'll eventually get to the point where you want some effects. That's why a modeling amp is great -- you get tons of built-in effects that substitute very well for a bunch of effects pedals.
Be careful, though -- some modeling amps are junk. Some have a lot of effects, but they sound awful. Play with a few until you can get one with the "sound" you want.
