Since we were talking about custom fitting your putter in the previous post why not consider making yourself a custom made putter? It's not difficult, does not require a lot of expensive tools and you will end up with a putter that will work as good if not better than those very expensive ones. You can easily adjust the weight on the following two examples. I believe it makes a big difference in my putting.
Take a look Golfsmith at:

You can get this head for about $50 and a shaft for $7 and a grip for about $5. A total of $62 and some change for the epoxy and double sided tape.
Notice that this head has a weight that can be replaced with heaver and lighter ones.
Or, you could go to Wishon at:

and look at his Smoooothe 6 putter. It also has adjustable weights.
