synthesizer

I'm looking for an analog synthesizer with a sequencer and a budget of $500-$1000. With this synthesizer I'm hoping to create a range of tones and sounds that I can use for recordings. The sequencer will give me the ability to record longer pieces of music and provide a greater level of control over the composition. I'm expecting the synthesizer to include features such as portamento, glide, arpeggiators, and effects like chorus, echo, and reverb. I'm also looking for high-quality sound production and an intuitive user interface for programming. It is important to me that this machine is reliable and is able to deliver high quality results for various types of sound.
