Ha, I hear you. I got into motorcycles 15 years ago, ended up with 6. Got into vintage stereo, ended up with amps and receivers stacked everywhere. Got into guitars....well you know how that ended. Addictions can be all consuming.
I believe a lot of forum members have other big collections
I am in the danger phase of motrocycles at the moment, although I am still at only one, but don't know for how long lol
