The only way something would be cheaper AND well made would be if someone huge was making it like a Korg or Behringer. I think your options will always be between cheap and affordable, or expensive and boutqiue
That's true. Although, I think the the quality of both the rg350 and the retroid pocket go looks pretty decent compared to something like the OGA. Also, I'm talking about the less than $150 range, not $40. The problem is it's a niche market and are only produced in low to mid size quantities.
