I can see why you'd want to start with a Verner.... the Verners inspire serious gun-lust, similar to the feeling I get with the Jacob Kuntz guns, or a good Rupp.
It's sage advice to get your feet wet on a simpler project. Not to say you shouldn't set your sights higher than your ability, because your abilities will grow with experience. However, if you set your self a project that is too complex, you can crash and burn, never to return. So you must take stock of your abilities, both as an artist and a mechanic, and see if you are up for a certain project. Part of this is how many guns have you built, do you have access to some originals to work from?
