I am glad to see an achromat chosen. They can be excellent performers for visual if one is not overly neurotic about a little color.
I have a couple of fluorite refractors in 3 and 4 inch sizes that are optically superb, but I seem to derive the most pleasure from my featherweight Brandon 3 inch, f/15 alt-az achromatic refractor. It is one hand portable and throws up beautifully sharp, high contrast images. The wide air-space design of the objective lens displays about half the color of a typical Fraunhofer doublet.
When my back is acting up, it is often the only telescope I can physically set up and use.
Sometimes I wonder if I shouldn't just keep the Brandon and sell everything else. So maybe it is the one...
