Yes, had stokkies, also chilli bites. Developed a taste for them since my first trip to ZA back in the late 80's
The Excalibur type of dehydrator, with the trays removed, is really no different to a regular biltong box - it has a heating element and a fan to circulate the air, just the same. You can suspend anything up to about a 10" chunk of venison from the top tray. The round dehydrators, on the other hand, are far less versatile. Where a dehydrator scores compared to a biltong box is that, as well as jerky, you can also use it for drying fruit and veg - with an allotment as well as a garden, that comes in handy sometimes.
I find making biltong is a great way to use up old venison haunches and fillet when I periodically empty my freezer of stock.
