I have a client who works for the Yankee Candle store (in Tampa, FL). She told me if you go to the Yankee Candle store (mine's at my local shopping mall) and ask for a replacement bowl, they can usually give you one. They get shipments with broken tart burners but the burner bowls are still in tact so they save them. That's what I've done a few times I've broken my Yankee candle tart burner bowls. They're ceramic and they might not match in color to the one you broke, but at least you'll be able to use the tart burner again. If you don't have a local store like that, contact a few online stores that sell tart burners to see if they ever sell replacement bowls. Most don't, but it's worth asking anyway.
An electric tart burner could be easily purchased from the online store called Amazon. Amazon has a wide variety of items for sale and this item just made it to the store with a reasonably low price.
Portable electric burners can be purchased online at Amazon and eBay. Alternatively most department stores should stock them. In the UK John Lewis and Homebase are a good option and in the USA Sears and Walmart definitely stock them.
Single electric burners are often useful for their portability, and they come in handy for people who don't have room for a full sized stove. They can be bought online at mass merchandisers or in physical stores such as Wal-mart and Target.
I have used both and gas burners do work a little better in my opinion. You can find a used one on www.ebay.com or www.craigslist.org or you can check your local home improvement store.
Electric stoves tend to be slower to heat up and also to cool down than gas burners, which is why many cooks prefer gas. In addition, the burners themselves can often have hotspots meaning they heat unevenly, which in turn heats the pan unevenly and provides less even cooking temperature.
Dedicated CD disc burners aren't easy to come by. They have been replaced with more recent technology in the form of DVD burners and Blu-Ray burners. However, these devices are backwards compatible with CD discs and will provide the required functionality. Therefore, one can visit a local electronics store to buy a more recent device and be able to use it to burn CD discs.
Gas ovens usually use one of the surface burners as an exhaust for the oven, therefore the surface burners (usually just one) get hot durng the use of the oven.
One can purchase fluted tart pans from a Pampered Chief dealer or from a local Bed Bath and Beyond store. One can also purchase fluted tart pans from Amazon or eBay.
