Open Office Spreadsheet, for the win. Going to upload it to a file hosting website soon, for security reasons.

Well I set an internal flag on Marveltoys.net that keeps track of the figures I own... at least for marvel. The others (transformers, MOTU, Simspons, Turtles, Star Wars, Dragon Ball, etc...) I just have to go on memory. Fortunately for some of those lines I got most everyone so it's easier to remember who I didn't get.

I have an iPhone and use the three brothers apps, he has em for MOTU classics, MOTU vintage, G I Joe, DC, Marvel, Minimates and some others. All apps have pics. I also put together a database that i update, currently at 1,267 figs and I'm still updating.

i use the good old fanshioned powerpoint , and make a list in word , just to keep ot simple and easy to use luckly for me i'm only getting the figures i want and like which today i have 26 but still want 6 or so more till my collection is finshed, i also use for marvel legends is a site with good images called gofiguretoys.com where it shows you most of the marvel legends and i pick which ones i like most out of those lot :)

Hey, I know this question is a little off topic but its related:

Where do you go to find 'checklists' to know what sets/series and accessories go with your figures?

I have a ton of Old TMNT and bit-boxes full of missiles that I'm not sure who they go too. Not to mention random other stuff. I know there are some places for Transformers, but not other series. Thanks in advance.

I would just start by typing the characters names fallowed by data base. For GI joe, go to yojoe.com, for transformers its either, tfw2005 or seibertron.com, he-man, well he-man.org of course, hope this helps.
