I've heard good things about both companies.
The only knock on NE Rigging
I was warned about and experienced myself two Summers ago, is they're good, if you can get them. Probably a casualty of their own success, but they seemed too busy and may over commit on jobs/timelines. We lost 4 weeks waiting for them to come out to the boat after repeated promises and no shows. I was told about similar experiences at our Marina during the process. We ended up using someone else as it was a small job, and I'd still give them another shot based on their universal reputation for quality workmanship. No hard feelings as they did apologize, but something to be aware of.
Since you're only buying the rigging
from them and don't need their services, it may not be an issue.
Your prices are in line
with estimates we received as well.
Good luck and let us know how it turns out.
