I find that as a prop builder, the amount of money one spends is irrelevant, as long as you get what you want for a fair price (key word being fair). People may or may not be too electronically inclined, so some offer services while others pay for them. That's great, it's a part of this community that I love: seeing others offer services to those who may not have the ability to do what others can't. Don't get me wrong, I cringe at the idea of anyone spending $1500 or more on a Graflex that may or may not be a replica, with a acrylic crystal chamber kit from FX forums that the person selling it probably spent maybe 30 minutes of soldering to put together. It's insane, but I guess if they really want it that bad, they'll do it.
I kind of look at my Arcann Mask as the pinnacle of my point I guess

I'll take a try at listing all the expenses that went into it:
Over 80 hours of modeling in Rhino (since it was only just announced via trailer)
$137 for a 3D print of the mask itself
$200 on Bondo body filler, spot putty, and assorted sand paper
$50 on paint
$100 on casting materials
3 weeks of perfecting every detail and edge of a rough 3D print all by hand
$15 for brass sheets
$50 for dremel and assorted bits
Over all, from start to finished product, I started modeling in August of 2015 and finished the mask the last week or so of December 2015.
The list is pretty extensive! But I love my creation because in every aspect, it's mine and my own. So, to me, I could have spent 3 more months and $1000 more to make it, and never would have regretted it.
I guess I'm going more on a tangent now, but you all know what I mean. We collect and build until we get the things we want, and sometimes that involves throwing money at it.
