To each their own, of course! I don't mind the expenditure for the complete kit and had budgeted for it. Again, IMNSHO, it was well worth it for one of the best replicas of this ship that I can hope to have any time in the next decade.
As to the resin accurizing bits comment... I don't understand that one. Well, unless you're talking about the old Sub-Level 3 / SMT / Timeslip Creations Battlestar Detailing Parts. Those definitely aren't accurate, tho at least give the R-M kit more detail.
However, there's an upcoming accurizing set coming out sometime this year that's 1,000% better than the old detailing set. It allows the builder to get a whole lot closer to accurate than they'd otherwise get. Mark did a great job hunting down approximate scale parts, modifying them as required or scratchbuilding some pieces/parts.
Otherwise, to get the parts accurate to the original studio model, you've got to spend a lot of time trying to track down those specific parts in the proper scale. If you're scratchbuilding skills are as poor as mine, that means research kits. And if you go that route, you've got to purchase a number of kits - and if you want multiple copies of some of those parts to place in the areas the model calls for, you'd have to by multiple kits or casting materials. For me, it's just easier & faster to spend a little extra money and buy accurizing parts.
Maybe I'm lazy or maybe I just want to get the model finished before the end of this decade. I dunno. If I could get my painting skills up to where I'd like them to be, I'd have already finished literally dozens of models, but that's another story entirely.
To me, buying some accurizing parts isn't any different than spending money on the kit in the first place. Sadly, we don't have companies like Tamiya and DML who have started including accurizing and/or conversion bits in some of their kits, particularly armor kits, for the SciFi community, so have to rely on what references are out there and those who have the skills to build us accurate stuff - which means we rarely get 100% accurate kits.
:shrug: To each their own, as I said above. We all have a different way of looking at things that are driven by our priorities, right?
