I don't mean to hurt their business but I've also had a similar bad experience from Vesalia.
Sent them a couple e-mails regarding a technical issue with an item that I got from them and they never answered me back.
I mean, I don't mind waiting for an item or send it back if it doesn't work properly, this is retro and alternative systems we're talking about... but IMO the worst thing you can do to a customer is ignore and keep him in the dark.. nnnnnever again.
On the other hand Amigakit has a good support ticket system, and if you need information they will tell you what's going on... so there is where I'm spending my money now.
Good luck.
