Uberti is reliable, Cimarron is a Uberti but usually finished better. Pietta is reliable but cheaper. With a little help you can do most tuning jobs yourself, they're not complicated mechanisms, or any gunsmith familiar with single actions can. I think you mean loading stand and no it's not necessary. There won't be enough of a spent cap to use to dry fire, most split apart on firing. If you simply must dry fire a piece of aquarium tubing will protect the nipple.
Thanks for beating me to the punch beagle.
