These things are somewhat rare since the company is out of business and the retail cost was $400. I have an opportunity to buy one for $100. I've built cheapo CPBFs, but I am interested if anyone has ever used one of these.
I use a regular hand held unit and it works well. But toys are toys and if you have $100 to spend, why not? I have heard good things about these units, but they are expensive, or they were. The company has gone out of business I think.
