And, it emulates two SID chips and has multiple modes (6581 and 8580), so it seems like a pretty darned good deal, honestly.
Real SIDs are pretty pricey these days, and they aren't making any more of them, so they will keep climbing in price for as long as people find them interesting. So, it's good to have an alternative.
Wow, didn't know normal SID chips went for about $40,- nowadays.
80€. You're right, it's not cheap, but I actually expected much worse.
