I'd recommend getting a few issues into it before you decide to go spending more money on 3D printed, laser cut or etched brass upgrades. You don't attach the hull plating for a long time, Issue 47 or so, plenty of opportunity to add mods. You'll also get a better idea of what's visible and what's not seen so easily. It will also depend on what you want in the end. Several guys have done absolutely gorgeous interiors (much of what you'll do at first is put together the cockpit and main interior section). As for me, I'm more interested in building the model for the exterior and pretty much just put the interior as it comes. I'll spend most of my time on the paint job towards the end. One problem that we all have is that we really don't know what's coming next or how it'll fit together in the end, as the kit is new and even the folks in the UK haven't got there yet. All the pictures on the covers are not of the actual model.
