I recommend the f&v 1x1 lights as well I have a kit of three I picked up used for a grand. Mine are bi-color and while I do wish I had the daylight version the bi-color works fine for me and I find the tungsten is true which is a problem with many other panels I also have some divas which are good because clients are familiar with the brand. Flo lights are also a good kino knock off brand I have used some of the four banks and put kino tubes I them.
My advice would be start with a cheap kit to bud experience or a reel with and spend the money to get the good lights that last. The arri, k5600 and mole richardsons are around because they are dependable and can take the abuse
