Welcome First suggestion is collect what you like- even for investing. That way if it is a dud you still have it and enjoy it. Second - read the posts here. I have learned a lot and taken suggestion that have been very lucrative but remember everyone has opinions and they are different. Third Develop a strategy and be happy with that strategy, Buy and hold, quick flip, part it out, used, everything on sale, big sets only, exclusives only, etc. are all strategies and every person here has one. Fourth, Time, space and money are all limited. Fifth, define your goal. Six, be realistic, this is work to be successful. My last two big buys were the ToO and Red 5. I am waiting for my orders but I think these are reaching the end of their run (in my opinion) and with points and a winter soldier I feel they are a good buy right now. (Just my opinion.) My longshot outsider is the Maersk EEE. IT is in stock but has a retiring notation. But I really like this set so it is more of a personal thing to me.,
