Electroplating on a budget - anyone have any tips?

I'd like to set up a basic electroplating/electroforming setup for nickel and copper, preferably without the enormous cost associated with most kits. As such, I figure I'd do most of the work myself. Here are my plans for the main elements of a home electroplating setup:

1. Power supply
This is the easy part - all you need is a big power transformer, a bridge rectifier, a variable current regulator, and an ammeter. I've found some decent looking current-regulators-on-chips, but they're all quite pricey - if anyone could recommend a good current regulator design, I'd appreciate it. (Low noise is not a requirement.)

2. Plating bath
This is not so easy. I'm told that a combination of copper sulfate and sulfuric acid works pretty well for electroplating copper, but I'm not sure if the same will apply for nickel sulfate and sulfuric acid. Most electroforming kits also include brighteners of various types to prevent the buildup of crud; if any one can suggest what I should be using for this, I'd appreciate it.

3. Conductive paint
The obvious solution is to go buy some, but at $30/bottle it's a bit pricey. The alternative are much cheaper graphite-based conductive paints. I'm not sure if the latter would work - anyone have any thoughts?

If the blackened layer does not last, there are several options.

1. If the surface is nano-coated or covered with an invisible clear varnish, this layer must be removed so that the bluing liquid can adhere.

2. The surface may be made of an incompatible material. 

3. The pre-treatment may not have been carried out thoroughly enough. Bluing will only work on a clean surface, free of dust, dirt and other contaminants. 

4. The bluing agent may have been too concentrated. Depending on the product, you may dare to dilute it with water.
