With all the various die cutters on the market I have to say I'm tempted to buy them all, but in the grand scheme of things... you won't use them all enough to get your money's worth. Before you buy, research and assess your scrapping style. When I chose to buy the Big Shot I did it for a couple reasons... accessibility to reasonably prices dies (most craft chains carry a large enough assortment and regularly have 40-50% off coupons and sales) and ability to use other manufacturers dies and embossing folders. Every die or embossing folder I've found available in a retail chain has worked in it. I may have had to add an extra clear plate, but it still worked.
I don't use themed die cuts, so where I save money is the dies that are versatile. I buy scrolls and other decorative shapes, tags, frames, borders and flowers. That way you don't spend money on a die that can only be used for a certain
occasion or holiday.
The flower dies I've bought in several styles and sizes. You will NEVER have to buy another package of flowers if you buy a few well thought out dies. You will be amazed what beautiful flowers you can create from scrap paper, glimmer mist, paint,
stickels, etc.
