Macallan,
You may want to check in with Brooks Berdan in Monrovia, Ca. He is a well-known analog guy (he famously developed mods to the early Oracle which the company included in its later versions of the table) and is a dealer for both tables. I don't want to put words in his mouth, but when I asked about SME vs. VPI, he seemed to like the HR-X better than the SME 10 but not quite as much as the SME 20. Happy hunting.
