Let me tell you what not to buy.
I didn't own a biscuit cutter, but was intrigued by the concept. I wasn't thrilled about spending $150+ on something I wasn't sure I would use much, but again, I was intrigued by the concept. Crusing around eBay on evening, I saw a no-name biscuit cutter for $16.00. How could I go wrong, as nothing more than trial tool. My prize showed up a few days later, and I discovered part of the fence to be broken. A few e-mails later, and I had another tool on my doorstep, no charge.
Needless to say, this thing is a galactic piece of crap. The lack of quality is laughable. The "fence" is made from the cheapest plastic, and is completely impossible to set / use accurately. To adjust the fence up/down requires partial disassembly of the unit. To return the unit to it's carrying case also requires some disassembly. The on/off switch is very sensitive, with the slightest touch turning the unit on (safety issue when making adjustments). I found that the blade on the replacement tool did not track true, and wobbled enough to create a slot much larger than even my largest biscuit. The blade on the original unit created a proper sized slot, so between the two of them, I assembed one "good" unit. I use it occasionally, and have concluded that I need to same my pennies to buy a proper tool.
Lesson learned. Don't buy a $16.00 biscuit cutter.
