What a great thread!
Yes, like bobward my loft is full of kits, some still shrink wrapped. I cannot go past Dominoes toy + hobby shop in Leicester without having a look. When you see a kit on sale that you made at the age of 8 it brings the memories flooding back (I'm now 43).
Now entering my 4th childhood, my attention has now turned to a 1950's railway layout. Will I ever want to grow up! - NO.
