I end up getting a mutoh 626uf with rotary attachment at the beginning of the year.
The biggest things I have found with uv is have stable environmental conditions.(temp and humidity). Spend the time to dial in your profiles. Understand the current supply issues that have been going on with materials and ink.(ink I stock a full set of cmyk 1 varnish and 2 white as a minimum level. Make sure you have a good service tech. (Victor at Axiom has been the best one I have found).
Once you get comfortable you will find more and more things that you can print on. Especially if you can make your own jigs.
