I came across this product
and I have found similar listings on ebay, amazon and aliexpress.
Has anyone bought this and can possibly provide some feedback/information?
Here are some more photos:
That white resin and the quality of the print are my main concerns. The company that provides the photoetch is familiar to me, I have purchased some of their sets in the past.
I have one. It’s worth it. The print quality is very good - well up to modern standards. If your concern is that the white resin is that slightly grainy stuff you used to get on Shapeways prints, don’t worry, it’s not. It’s smooth to the touch - seems to be white resin to me not PLA.
I had the same concerns as you and went for it. I figured that even if one came out in plastic in this scale (it’s the only ship of it’s class) by the time I’d bought all the brass, turned barrels, wooden deck (assuming they were produced by the aftermarket companies) the total cost would be approaching this. So I waited for a discount run on Aliexpress - the eBay prices are not dissimilar - and it arrived from China in less time than expected. I wasn’t disappointed - it’s a lovely kit. The biggest problem is not with the kit - it’s finding the time to build it 
I’m a real model shipbuilder btw with no affiliation. Hope that helps.
Thank you for your answer. If the resin is good then I am more than happy to work with it.
I am building a 3D printed 1/72 submarine at the moment, if the resin print quality of Vanguard is similar then I find the price logical.
Is there any chance you can share photos of the kit? Not the metal-photoetch parts, mainly the superstructure and the gun turrets.
Here you go. I angled the superstructure pic so the light shows the surface relief. I tend to find iPhone photos really show the imperfections but it’s smooth to the touch. The detail isn’t quite as sharp as your resin 3D Sub but perfectly acceptable when you consider what you’re getting.
Looks quite good, the imperfections will be easy to cover with a good surface primer - filler. I am definitely up for it. 
I agree and I also use commercial filler primer or Mr Surfacer 500/1000 spray and then sand for this type of casting.
