I am looking into buying my first 5 string bass. I own a 4 string Warwick corvette std but I want to make the transition into the 5 string basses. I LOVE WARWICK but THEY ARE SO DAMN EXPENSIVE EVEN USED!!!

What is a good bass that is a 5 string I can buy. I am looking for these characteristics:
1.)Good all around bass, I specifically play progressive metal however.
2.)Comfortable feel and easy to take care of
3.)Good tone
4.)Easy to learn 5 string on
5.)500-700 dollar price tag, used price is included
Any recommendations are a big help. My number one choice would be a Warwick thumb 5 if I could find one for that price (knock on wood), but I need more choices. Thanks!
