When a supplier does something right, I believe in spreading the good word to fellow modelers.
I have purchased many items over the past ten years from CultTVMan (Steve Iverson) at http://www.culttvmanshop.com/
I have been delighted with his fine service on every transaction. On the rare occasion when something did go wrong, he immediately made it right.
For example, I recently purchased a kit which turned out to be missing some parts, even though all the bags were sealed. Not only did he exchange it for another, he sent me a pre-paid shipping label so it wouldn't cost me anything to return it to him.
His web site is not only a store, but also contains a large showcase of customer-built models with comments by the modelers, including an interesting forum, at http://www.culttvman.com/
Anyone interested in Sci-Fi modeling will be well satisfied with this merchant! I highly recommend him.
