I will be visiting Boston in late October.  I am interested in who you think the top four providers  ( your bucket list) are.  I have done some research on my own, but wanted some fellow hobbyist's opinion.  Ladies feel free to speak up as well.  Thanks for your help!

be a bit more specific on your requirements, needs, etc., and you will get better responses

Thanks for your comment.  I could always say  looks -10, performance -10 and great conversation.  I thought I would just leave it "wide open" since we all have an opinion of  what each one of us like and why
