As I replied in my earlier post…Aurender N10, Lumin u1 are definitely worth looking into. I’ll add the Aurender N200 and Lumin U2.
My preference would be the Aurender because of better build quality as well as better UI. I honestly don’t think the lower model Aurender N100 will get you where you want to be although it might be relatively close.
As to budget…you’re probably looking at a price range of $3,000 - $4,000 on a used market and $5,000 - $6,000 new.
