I've been afflicted with the addiction for a few of these.
Luckily I never did the Quarters set. I did get the engine though to pull my patriotic cars (flag cars, etc).
I avoided the Monopoly Boxcars, realizing that was going to of course be a large set from the get-go, though I did get a couple of the non-boxcar issues. (I too started with the cars from the old Eastwood series, though I never did get the original Mint car, and I did not get the 3 engines Eastwood offered either) I did get the more recent (2009, I think?) Monopoly steamer and caboose. I also got what I think might be an RGS product - a silver GP with caboose done for Monopoly (I did not buy this directly from RGS, so that's why I am not sure if it's his or not - I probably acquired it years after it was made) There were a few other RGS cars - I got the flat with Submarine, but didn't get the Generator car (there may well be others).
I started, but knew I would resist completion for the recent Presidents boxcars. In part, I wanted to support the Made in USA effort. I bought the first 8 and then Reagan, but I'm probably mostly done except for maybe one or 2 more if they get around to doing them anytime soon.
I re-ignited my late 2000's Disney affliction by recently filling in my blanks for the operating cars, which I had avoided when they were first issued. I sort of look at my set for those as completed at this point, if they re-visit the Disney license, I would probably consider it a new series and not consider too much of it.
I may be in the minority here, but I group Lionel Disney into 3 sub-groups:
- the late 70's series of boxcars (with engine/caboose),
- the 90's series of boxcars, 3 operating cars (with engine/caboose),a few handcars, and 2 accessories,
- the 2000's series of (I think 5, or was it 7?) boxcars, operating cars, and a few handcars. The lack of an engine/caboose specifically meant to go with these sort of dilutes this latest series, I think.
There were also the starter set offerings, but I don't collect those (though I may have a few cars from those sets).
Long answer to short question. I guess I should have just said, "yes, but I'm trying to reform my habits!".
