Ive bought things from Vesalia for about 400€ (~500$) over the last month and all orders have been quick and everything have worked fine, no problems at all with them ever.
I have no problems with Amiga kit either, spent 100-150€ over the last month there without any issues, it takes a bit longer to receive the packages sine the payments are on pending a lot longer then vesalia, but in the end no problems and everything works.
Both a great places to shop at for Amiga users, I don't favor any of em over the other, I buy where the stuff I want is in stock
This is my personal experience and I have never had problems with any of them ever in the past. Tho I have been lucky and never gotten anything that was defective (besides a cable once but that was just a simple solder joint I had to re-solder)
