chocolate vs cheese fondue

[FoodFascist]

My grandparents would have loved a fondue set for xmas. For cheese fondue, not choc. I've had a browse and it looks like the more affordable ceramic sets are all (or mostly) advertised for choc fondue, can those be used for cheese? I can't really afford a cast iron one at £50 and up, especially as they'd only be using it once or twice a year. And stainless steel ones might not be so great either, I can see cheese burning in a steel pot.

They're usually quite different in size.
The chocolate ones are smaller than cheese ones. (Probably the reason for the price difference!) People eat a lot more cheese as it's a main course, not just a dessert.
Both chocolate and cheese ones are ceramic.
The metal ones are for stock/oil for meat fondues.

Lakeland have one for £14.99 and they say it is suitable for cheese and chocolate. Rather mysteriously they say it needs a gel pack for heating. No idea what this is, we just put meths in ours, and the picture looks identical.

oh thanks for that,
I'll see if I can't get a cast iron one in xmas sales or on eBay (grandparents live overseas so no chance they'd get their prezzie in time for xmas anyway, i might as well wait till their wedding anniv in Feb). Otherwise a 6-person choc set may do them well enough for a smaller party. Thinking about it, some of the choc ones I've seen are as big as 15 cm dia and about as tall, and cheese fondue is very filling so a 6-person set may well do them for a big party as well, esp. as they'd almost certainly have some other food on offer.
