There is only one "perfect" putter, it might be made by Scotty Cameron or it might be made by Zevo. Only you can find that out. Spend an hour several different times trying out every putter you can.
Scottys are indeed works of art and I would love to own a Del Mar but it would never leave the house since I don't want to scuff it up and it's still the wrong one for my game.
Over the last few years I have acquired 5 different putters yet I keep coming back to my 20 year old Ping B60. My putter is really one of a kind and it is the right one for me. I have had it tweaked for length, loft, weight and grip all by a professional clubmaker and putting instructor.
Now all that being said I will set aside my own advice and demo the new Ping Nome when it's released since it just might be my "more perfect" putter.
I bought my Del Mar 3 Pro Platinum almost by mistake, my old sticks got stolen and I was outfitting a new bag, the Scotty was a used but absolutely mint for $75. I bought it in 2003. At the time I didn't know Scotty Cameron was any special brand, just thought I bought a Titleist putter with really good feel. After coming to this forum I looked it up and saw it was only made one year (1999) and that these things are relatively rare and expensive. It was my antique roadshow moment of the day.
Just got it regripped for the first time, lol, and was posting in another thread how nice the golf pride pistol grips are...
