Not buying an MM, TOTAN, CC, AFM & MB back in the late 90's when I had the chance to get them at a great price.
I just didn't have anymore room as I already had 5 in my 2 bed apartment in North Sydney at the time and leaving them in the garage wasn't an option really as I had a break-in previously. I had a Qantas pilot living next door and did ask him if I could put a few in his place (he was single) but he had too much crap in there already.
