Specific Turnkey Providers

[David Rosenberg]

I know there are threads on this topic, but they are scattered and hard to pull all together. I have one main simple question:

Can people please share their experiences (good or bad) with any Turnkey Provider, regardless of market?

I am not interested in debating the merits of Turnkey vs other strategies, I'm just asking if one decided to go turnkey, who people would recommend (or not).  Of course sharing more details would be appreciated and valuable to all!
