Spence, that looks like a cool program, I belong to the Burlington club and we are thinking of starting operations soon and that looks like a program to consider.
I am currently using the box to bench to shelf system (plus an A-line style case for what comes to the club.) This works well for the current stuff. What I am dealing with is combining my collection with my fathers and keeping track of where things are. My father collected for 60 years without ever losing interest, so he left me with about 15 Rubbermaid boxes of engines alone. Every couple of months I go searching for something I remember and it's like Christmas because there's a ton of stuff I don't remember having. (This may be an age issue, lol)
I am playing with an Ipad app called Procollect that seems to be a generic version of what most have suggested. I think it would do the trick, but it would be nice to have something preconfigured for trains.
As for excel, I don't have any issues using Excel, I use it at work all the time though so I wanted to do something different at home.
My home Imac was in for updating a couple of years back and was found to be "un updatable" the techs told me that they think it might have been Imac #75 due to the serial number. Decoder Pro works fine on it and I think it has An old copy of parallels as well, so might go that route so I can run Yard office eventually.
Thanks all, went from knowing nothing to having everything I need to make a plan!
