You will always get people who are totally against circumcision... so you probably have to be prepared for negative attitudes towards it.

There is no "right" or "wrong". It's totally a personal choice. Circumcisions have been performed for 1000's of years. Until the 70's most boys were circumcised - regardless of their religion... then it became unpopular... and recently it's been in the media again.

I will tell you about my experience.
My husband is Jewish - although I am not.
because I am not - then our children are not recognised as Jewish.
But when we had a son, it was important to my DH that his son be circumcised. My father and all my brothers are circ'd... and I was not against it. Although my son is not 'officially' Jewish - he will be bought up with Jewish traditions.

So... then we had to find someone to do it. Ideally we wanted a rabbi - but even the more 'relaxed' synagogues wouldn't recommend anyone. We found a Jewish doctor who was willing to do it. Then someone recommended a Rabbi who would also do it - and he agreed.

We had the 'ceremony' at home - with only my parents present. (The Jewish often make it a huge party). As per tradition - it is performed 8 days after birth.
In honesty - I was expecting it to be quite traumatic... but my son just lay on the table... and the Rabbi performed the circumcision... wrapped it all up... and it was over in minutes. My DS cried - but not screamed. And as soon as he was handed to me, we gave him his bottle... and he was fine. Stopped crying. In fact... he would cry more when we used to change his nappy.

There are a couple of methods... I think the one you refer to is called the plastibell. If you click on the links that Tanya has provided... there will be more information.

Personally... the only thing I would recommend - is if you do it - do it as soon as possible after birth. I imagine it would be a little more traumatic the longer you leave it (like months or years).

Good luck with whatever you decide. You are not horrible parents if you decided to go ahead with it.
