>>7667443GFFMC Wing Zero Custom is monetarily the most expensive toy I own no doubt.
Unless you count my LEGO MOC spaceforce carrier - fucker's well over 25 lbs unembarked. Going by bulk pricing it's north of $300, much more including crew and strike complement. However the least expensive is a tough one.. I have a couple toys from childhood, and smaller sets of lego including collectible minifigures.
Well going with the carrier as it's easier to imagine a success using Toy Story rules it'd pelt the intruder with the spring loaded deck weapons and those of its strike craft. Targeting the eyes or the mouth/throat could cause incapacitation through temporary blindness or suffocation. A small strike team of Spectres would be deployed to locate a telephone and signal for help- using their grappling rope they'd be able to scale the furniture where the landline we keep is, topple it from where it rests and activate the buttons. If that fails there is also the option of activating the alarm system if it was not enabled before leaving the house (buit it nearly always is). It doesn't take long for police to arrive if not deactivated upon entry- I've forgot to do so once, was very distracted by some music so I didn't hear the ringing.
