Magic ,
I've built about 12 of the Tamiya P-47's bubbletops and razorbacks . The 1/48 scale your thinking of doing is an excellent choice to get started back out on . However I'd make one suggestion , I notice that your looking at detail kits for your model as well , if your not fimilar with them they can be a real nightmare , the PE is the worst when you first start using it , I ruined 2 detail sets for a Corsair before I became more at ease with it 2 doesn't seem like much , but at anywhere from $9.99 to $24.95 a pop it adds up . I'd get a reference guide and a PE folding tool , some will say it's not worth it , but beilive me it is . And most of all lots and lots of patience . Good luck and post some pics of your progress.
