I got mine free, kinda
I purchased QB Bills (Pan-es-ian) entire collection about 6 months ago (complete, minus 7 super rare carts and Top Gun LOL), and he threw in about $2K worth of accessories, extras, etc, after the deal was made (like a CIB War in the Gulf, CIB Top Loader, 20+ repros, Boxed Top Loader Game Genie, lots of PAL-exclusives, Game Sounds, GAR, 2 full sealed Aladdin sets, and about gazillion more things I'm forgetting). He's the reason I started collecting accessories! I had to at that point, since I instantly had a decent collection of boxed accessories.
