Thanks Robbo for your comment. For the Famo, the only thing I can think of is the Aber upgrade set. Actually I only been doing this hobby for around 8 months, so I am not knowledgable at all, (but been in love with the German armor for a long time). Just off my head I can think of a number of people whom are much much more qualified to answer your questions in regarding to what kit to avoid, or what to use:
Folgore : For his great knowledge in history stuff
Sgtreef/Pak40/Avukich : They are all very well versed in German armor, and construction technics, and AM stuff. Actually it was Avukich whom hooked me into AM stuff....
Sabot : Man, he is a guru of kits.... #:-)
But if you elect to use Aber PE sets for Famo, please do not be discouraged by it at the first place. The first Aber I used was for my Jagdpanzer L/48, I used 3 pcs of the whole thing, second one was for my King Tiger, I used 7 pcs, and third one was for my Stug III, I used about 20 pcs. Now I probably can use up to 75/80% of the whole PE sheet. So all I want to say is that it takes some getting use to, and once you do it, it's more demanding on patience than skill. And you need good tools, and always put your CA glue on a piece of wax paper and apply glue with a pin to not over apply the CA glue.
Good luck, and thank you again.
