I started 3 spreadsheets ( Autos, Decept, others) of the TFs I have when they reached around 300. Just so I don't loose track of what I need ( figure/parts wise). Its mainly arranged basically by series and faction. G1 first of course and so on. When I do insert a newly acquired bot I just insert it in the last as per series. Ive set an automatic adding formula at the bottom of the column for "how many" ( as I do have multiples) so it just updates automatic on how many I have. It does pay to make a list , keeps you focused on what to get, but if your not into a lot of series anyways - eg your only after MAsterpiece and G1, then it can still be helpful as a quick database for your personal reference.
