Personally, i don't think there is any "best putter" it is all about how it feels, so i think you should go to the nearest golf store, or dicks/Sports authority and just putt around, call me insane but i'm a golfer who like to lean way over the putter, so i picked up a junior putter for 25 bucks, it has a nice soft insert and a weighted head, it feels great and got rid of all my 3 putts 100% no joke, this was on 3 18 hole rounds, and i 1 putt much more even from around 15+ feet out. So honestly, putting is all about how it feels to you, also if you are struggling, try changing your grip.
