Elena just cut some Siser glitter vinyl and it cut easy and applied fine.
Renae, you want a machine to cut heat transfer vinyl. My ex-wife bought a Silhouette Cameo 3 and she's very happy with it. She chose it over the Cricut because that one requires that you be online to use it. There's also the GCC i-Craft. I suspect most here, that don't use a "professional" cutter, use a Cameo. You can get one for a little over $200.
After cutting the vinyl you need to apply it. This requires heat and pressure. Some vinyl applies at a temperature low enough that it can be applied with an iron. These include Siser Easyweed, Joto 4-in-1, and Thermoflex Turbo. Glitter vinyl generally requires a higher temperature and should be applied with a heat press. A heat press would give better results with the other vinyl, too.
Chinese-made heat presses, with no warranty or dealer support, can be bought on ebay for as little as $200. Prices, and hopefully quality, go up from there, with really good ones going for about $1500.
There are a lot of videos on youtube that can help you get started.
