I am expanding into this one ATM bit by bit,
Still lots to learn about the hobby but I have amassed a great collection of real beauties and a FRAG saw will be in my future I think. I have broken past the stage of keeping things alive and now there actually growing out. Which is a big hurdle for many beginners I must admit. Good information and advise is hard to get sometimes and the club has done wonders with respect to quality advise and help in the hobby.
