Vortex Sound Research

Hey guys, so I've been playing guitar for about 8 years now and have recently been thinking about getting into synthesizers to change things up. I'm mostly interested in using it to create ambient soundscapes but capability for other kinds of sounds would be nice too for varieties sake. I'm completely new to synths and keys in general so ease of use is important to me. My budget is about $500-$1000. Thank you!
