Fully agree with Bobk, DickyD and Colin Bishop, the early kits suffered from some poor quality mouldings, the one that stuck out for me was the torpedo tubes on the Solebay kit. I often visit Ron at Deans Marine to get bits and pieces for all my warships namely my HMS Coventry and now my model of HMS Berwick, and have seen the continuous improvement in the mouldings. I have known people criticise Deans Marine kits over the years but like Colin Bishop mentioned, where else are you going to get that huge range of attractive models?
Some of them may not be beginners kits but if you can't make a kit with some little flaws in the kit, where you can replace the parts if necessary, try scratch building. I have and often use the Deans Marine kit part as a guide to scratch build the item, some may say thats not the point that you should have all the parts made perfectly for the price paid but I have found that the Deans Marine kits are reasonably priced and often value for money because where else are you going to find a fitting that is unique to the vessel being modelled?
