For around 280 USD, you will have a full blown synthesizer and a full studio, which is peanuts when you realize the synthesizer alone will run you at least 400 dollars (Not even a high end one either). And, if you need any help setting all that up, feel free to PM me or post on here.
OR
If you rather have a standalone synthesizer (which I don't think is the right way to go for a beginner, but your choice), I always point people to these two:
Roland SH-201 Synthesizer
EXCELLENT synthesizer for anyone, especially beginners. It literally has a road map on it to show you how to make a sound. When it comes to leads and supersaws, you cannot beat this for that price.
Alesis Micron Synthesizer
Gorgeous synthesizer with very warm analog sounds. The pads on this are phenomenal. Unfortunately, not as beginner friendly as the SH-201 (Although the presets on this are really good).
I have personally used both, and if you do decide to buy a synthesizer, you cannot go wrong with either one of them. After I buy my Access Virus TI Module, I'm definitely going to save up to buy both of them
