Heres the deal,..I can get a Colorpoint flasher from a guy that claims that health problems have caused him to have never used it. He got it a few years ago still in the box and it looks like its never been used. He wants 100 bucks for it, might take a little less. Having never used a flasher before would you get this or buy a Vex? I realize that some like the vex fl18 and I imagine it is a great unit but how would you compare the colorpoint compared to a say to a f8? I understand that some really like the colors of the vex over the Colorpoint but are their many-or much differences?
