I just remembered that one dealer near me sells windham weaponry, which is owned by the previous owner of bushmaster. I've heard really good things about them in reviews and remember when holding the gun it felt very nice and the fit and finish was great. Also buds has the ny compliant models at a great price.
If buds already has the compliant models and you like the price then I would go for that. I do not live in a restrictive state so I can't really help you with how long the process would take to make it compliant, but I am pretty sure that the dealer who goes through the process to make it compliant will charge you for labor as well as the transfer fee.
Windham makes fine ARs, and I would not hesitate to take one over an RRA. You will be very happy with either!
