My very first unit was a Lx3. I sold and traded of many units to find my favorite. I didn’t really get a chance to try the upper end units. I have been on a college student budget for quite some time. I may have even spend some of my student loan money on a flasher. I’ll be paying that one off for the next 10 years! I am back to my very first flasher. The Marcum LX3tc and couldn’t be happier. I would like to get my hands on an LX7 but my time will come.
