Donna you sound like me. I am a bit of a pyro enjoying clay, glass and a little metal work and joke about being a kiln collector. (4 but only 1 useable currently)
Purist who do fine glass work will tell you you need a separate glass kiln with elements in the lid for more even heat. However you can do a lot of glass in a ceramic kiln with a computer controller. Glass needs a ramp/hold firing schedule where the temperature is held at certain stages. For slumped wine bottle and fused jewelry a small ceramic kiln will do fine. And I 've found I really don't have to do that flash venting or opening a hot kiln to cool the glass. If you use slump molds or firing paper you can use the same shelves for glass and clay.
Kilns designed for glass may not get hot enough for your claywork especially if you like stoneware. So a ceramic kiln would be a good start for you. I'm partial to Paragon Kilns because they are in my neighborhood and that's what has been in all the schools where I've taught. There are other well known brands that might be in your area and they all work about the same and you can go crazy trying to compare their different extras.
The big thing to check is the wiring and plug. I got a hot deal on a big used kiln but after taking 3 people to haul it into my garage I found out that the big plug was not the same as my dryer plug and it would cost more than the kiln to have the house rewired with the 60 amps it needs. Check you house's fuse box to find out if you would have enough wiring if you get something bigger than a standard outlet.
Good luck finding a kiln.
