I'm in the UK so what's available here will vary a bit from what's available in the US. I realize international shipping is an option, but that's just an extra cost, ya know? But I was looking around on eBay and different 1/6 custom sites...a quality body can be found for 15-20 pounds (about $25-30), I was unable to find the jeans recommended for less than 25 pounds ($30-35), same with the blue hoodie, the green jacket was around the same...didn't bother looking into hands, socks or shoes, or a bag and camera. With the small bits I was looking at, it was looking like 65-80 pounds already which would probably be about 90 to 140 dollars or so.
Maybe I'm not looking in the right places. I don't really make custom figures...I've made one before; a Cobb from Inception. He was pretty cheap considering all I needed was a body, head, gun, and suit (and all the pieces for the suit came in a set together).
It's just wishful thinking for me right now. I've spent way too much money on figures lately, to the point where I'm starting to feel guilty about it. I know I'm getting some for Christmas, as well, and my husband recently spoiled me by buying me a bunch of TMNT figures. The Peter kitbash isn't so expensive that I'll never do it, but right now, with the places I was looking at, it's just too much for me right now. And I'm really impatient with things like this...I wouldn't want to buy just a couple pieces now, then buy a piece next month, and so on. I wanna buy it all in one go!
