Ive only used a cheap radio shack md and found quite a bit of stuff. I decided I would invest in a better machine. I just hope I didnt bite off more than i can chew. Originally I was going to buy a fisher f2. Did more research and decided on a f4. Did more research and changed my mind to an f5.Any tips or tricks I need to be aware of with this. Is this really that hard a machine to get used to? I dont plan on buying any other machine for quite a while. Hoping I can grow in to it. Would like to hear from others that bit the bullet and bought a machine hoping they could grow into it. Any thoughts on it? Anything I should know upfront? Thanks for your time. Cant wait for spring.
