The final reason to be leery of home parties is scheduling new parties at a party. The system is supposed to regenerate at least one party or show from another, but you're not always that lucky. If possible, try to schedule yours around the different holidays. This can be an incentive for party goers to agree to have a party of their own.
In the end, of course, you can’t really decide about a home show without trying it out. I suggest getting your feet wet with an informal get together and then see how it goes. If you make some nice sales, then it may be worth your time and effort to organize more formal shows in the future.
