@ manny,
Hi - yep its the Spyder for me.
Its the only one I've purchased so far, but after the initial trouble just getting use to something different to the basic putter, I'm very happy with it.
Was about to drop it and go back to the basic putter, when someone posted me and told me to stick with it, practice, practice, practice - which I did, and now I love it.
The art of shotting real low is to get that second / third shot in real close so you just have those 5 - 10 ft's. That said you're not going to get that close all the time, but for me the Spyder works real well.
Shot my best round yesterday at Kiawah - 61. Should have been 59 had two total brain fades. But single putted 13 greens - which is not bad. Not all 5 ftrs either.
Hope that helps.
Cheers Doug
