One “law” I found out is that if it’s on sale or you see it, buy it.
There are modelers who say that kits will be reissued or recast. Nope! Not for resin. They think that it’s “law” that if you miss it, it will reappear again. Nope! The “law” is that if you missed it, you missed it.
I just missed an ETSY kit sale for 30% off because I hesitated to purchase. 30% off and FREE shipping from overseas is huge good deal! I contacted the seller asking him when his next sale will be, so I might see 30% off again as the kit is 3D printed and not OOTB. But it is “law” that if one missed the sale, one missed the sale.
So if you see it, and can afford it, bite. (So I took advantage of another ETSY 30% off seller’s sale with FREE shipping because these ETSY sales are on countdown timers. Caveat…ETSY sells some really awesome 3D printed kits that you won’t find on Shapeways, plastic, or in resin).
Another “law” is that with model kits, it’s similar to Moore’s Law regarding CPUs in that with CPU, technology is exponential in CPU speed and processing power as technology gets better and advances. New CPUs and chips can cram more microprocessors and gates into CPUs, increasing functionality, speed, power, and computations.
The same is true with model kits. Kits of 2023 are way more detailed and accurate than kits from 1980s and 1990s, obviously. The technology, skills, engineering, casting, and machinery and molds are way better now than years and decades past. eBay is populated with vintage pre-1990s plastic and resin kits that are long OOP and don’t sell because no one wants them due to their lower quality and casting no matter how rare they are.
So when shopping with “kit technology law,” a keen eye to detail and accuracy grows with age and experience, just like the computer processing power of Moore’s Law…new kit releases and newer CPUs get better in the future, not worse.
