They don't exist yet, the second half of october are the very first units offfered.
Too bad I was hoping for a much sooner date. but waiting until oct 31st makes them pretty much a sure loser.
I have always wanted to try their gear. And I missed the sp10 when it was an in stock purchase as it was just a bit too much for me to buy.
This one has a better price point 1309 usd shipped to New Jersey , but waiting until OCT 16- 31st kills the value.
