You can get some really good deals on used Ibanez and Jacksons, but make sure the Jackson is an earlier model. They were bought out by Fender in '02 and there is argument over the quality of the new models.
I wouldn't recommend anything other than a Marshall amp. You can also get a decent priced used one at most music store chains.
I always say, if you are a beginner and/or don't have a ton of money, go used & quality over new & cheap.
