Have you ever looked at the church of Christ? There are many bad stereotypes out there about the church of Christ, but I have been attending my entire life and I find it closer to the 1st century church than any other church I have studied or visited.
The International Church of Christ, aka Boston Movement, is an authoritarian, abusive organization, IMHO. One of my cousins is a member of it, and he's been used and abused shamelessly. Sorry if I offended you, but that's been my experience.
The mainline Church of Christ is just a good church, even though there was no musical instruments allowed at its services. Although I did not like it enough to join, I have good memories about the times I attended their services. Excellent, generous, salt-of-earth Christians
