I'm considering the Joye 510T...I haven't been able to do an extensive amount of research, and would like some quicker advice. Is there another model that's overtaken the 510? I know it was one of the best a while back, don't know if it's still the most popular. Also, where would be a good place to get whichever model is suggested? And where's a good place for getting DIY juice materials? Thanks in advance.
