I'm wondering. did this individual take your money and then 'push you out' ??? or did he simply decide to go ahead without you(r cash)?
either way, it sounds like a stab in the back. it sucks when people don't honor their own word. if I were you, I'd be pissed too...
....but if I were you, I'm not sure that I would sell off all my stuff, based on the indiscretions of a single "individual".
in my experience, MOST of the people involved in the hobby are decidedly more honorable, than this one "individual" has revealed himself to be.
my advice: don't do anything you'll regret later. don't sell the Shrine. if it troubles you to look at it, then box it up and get it out of sight (out of mind). if you still feel the same way in a month, then let it go; if not, then unpack the boxes, and set things to right.
I have fond memories of Master Replicas, circa 2002-2007(RIP) :( I love my Vader Bucket. I won mine, playing trivia with Amy.
that , in itself, makes it special. and that wouldn't change, regardless of a(ny) unscrupulous "individual".
that type of "individual" can be found everywhere, afterall. from the dealer who ripped me off on my first car, to the contractor who ripped me off on my home renovation. :-\ I refuse to give those people the upper hand.
don't let this guy ruin something you care about, or he will win out in the end. remind yourself of WHY you built your shrine in the first place. I'll bet, it had nothing to do with anyone else but yourself. (you weren't out to impress anybody. you did it to satisfy your own passion for something intrinsically cool. much like my own MR display: anyone who doesn't like it can 'kiss my shiny metal xxx'). :-*
I've been burned on props before too.. but that didn't sour my collection. (instead I just lost faith in humanity ;) bwahaha!)
