I dealt with him in the past too and what a stressful experience! I guess I can consider myself lucky because I did end up getting my kits ( a Bwing and an Awing), but same experience other than that : when you contact him, showing interest in purchasing from him, he replies immediately, but once he got your money, it's radio silence and you have to harass him to get any word from him. He would only reply to one out of 3 messages, with many days, sometimes weeks between replies, only to not really answer my questions.
And then you get all the BS excuses in the book : missing parts, too much humidity to cast resin (for a kit he said he had in stock ready to ship), sent the kit to the wrong guy (may be true, but again, who doesn't double check the address before mailing a $1200 package?), a hurricane, health issue (again, maybe true, and you can't say **** or else you're a monster, but when it's after months of delay and ghosting, you raise some doubts). I don't recall everything, but it dragged on for nearly a year.
