I would really appreciate some assistance finding a good, dual, tracking supply. This thread seemed like the right place to ask. Basically, what I need is a supply that I can use to troubleshoot and repair the beta22 channels that I have as well as some other projects that I'm working on so the minimum requirements are 0-30V, .5A (on both the + and - rails) and I certainly wouldn't complain about additional power or features. Budget is somewhat flexible, not looking to spend a ton, but I do like nice tools. I'd pick one on my own but I've been getting mixed reports about supplies that are stated to be "dual" that really just have two outputs and can't to + and - rails.
