The problem is that he was using OOP ALPS printers to print all those great decals that had great opacity, silver & gold accents, and of course printed white as well. No other laser or inkjet type printers can do that, so anything that you print yourself will not have the same level of finish quality. His decals were almost as good as the original screen printed decals - almost, because they scratch a lot easier. But in other ways, some of his stuff was actually better looking.
The issue is that the ALPS printer was a home-use grade machine, not designed for the duty cycle of commercial printing. They have complex, multipoint heads that are delicate and expensive to replace. They used to be sold and serviced by Best Buy, but since they don't exist anymore, that's no longer an option. Gord explained to me that a group of the original staff from ALPS bought up the tooling and repair equipment and started their own business to handle service. But they are Japanese, and thus located in Japan. But that's the only choice. But as the printers are OOP, parts are aging, spares are dwindling, and the costs to keep them going are rising. The hassle in keeping the machines in service wasn't worth what he could get out of them, and the repairs aren't necessarily long-term fixes either, as I pointed out before. So, crowd-sourcing doesn't really help the long term issue.
You can buy an ALPS printer on eBay still, even ones that claim to be reconditioned. Gord apparently has a number of them. But they are old enough that they aren't long term reliable anymore.
Now, back to the issue of your Phoenix, maybe someone has the decals that they'll part with (I'm not selling mine, I'm redoing my Phoenix as we speak). But even if not, the color combination might lend itself to printing your own decals on a laser or inkjet. The trouble there is that printer design assumes that you're printing on white or near-white media. There is no white in the ink. The colors are blended so that they look correct when printed on white backing. So, home-printed decals won't work as well on darker color models. However, your rocket is to be painted white, so it might work out.
