I also bought a Primus 8R Hunter stove (the one in the blue folding metal box) off eBay, good stove but I prefer the similar Primus Svea 123R.
Interesting. Same conclusion that I've arrived at. They're very similar stoves. Many of the parts are even interchangeable. But dang I like my little Sveas. So little to go wrong. So compact. And such good stoves. Maybe I'll have to sell my 8R's (one working, one needs a little love).
Um, I don't have that problem. No I don't. Not even close. Please don't talk that way; my wife might hear you. lol.
