Exactly where I picked it up at.
I have always gotten excellent service from Derek, although I may have to wait for him to get something in for me. But usually my order arrives within 7 to 10 days if everything is in stock, just remember to use the airmail, he even warns you of the extremely long shipping times for surface mail.
I bought this one either last year or the year before, sorry don't really remember, but the old dollar was worth a lot more then so naturally the price was a lower, but it's listed at $9.23 today. TM Diorama 3527 - Ruins interior with stove (1/35)
As for the thickness of the plastic, it's a little thinner than Miniarts. The bracing is just the old left over plastic that was trimmed off, and a hold over habit from my old doing vac aircraft days. Any thin areas was filled with CA. (Another hold over from the aircraft days) The two walls had a picture frame on them, I also back filled these and sanded the walls smooth.
As I said, you get everything you need to do the basic building, the rest is up to you. Besides the stove, a table came with it, and also the one rear full window. (that still needs to either be cut out, or probably I'll use it for a template to scratch build one.) I think the stove also needs a chimney, so another thing that will need a little scratch building. I also added the front floor beam, and rear beam that can be seen, and opened the area between the ceiling and the floor. As I said so far it's been a pretty relaxing project. (something I need to get me out of the modeling slump I've been in.)
This project is really unchartered waters for me, so it's going to be build, make mistakes, and everything else along the way.
