I'm really not sure if any of the currently made scales are worth the money or are the best. Normally I'm not all about something the weight of a brick being an indicator of quality... except scales.
If you want the best, look for ones that were made many decades ago. The heavier and more solid they are, the better.
I don't have the Lee scale, but given all the other things Lee I have, I'm willing to bet it works fine, it just looks like cheap junk and is cheap. However, one feature of it that I do like is that it is a 100 grain capacity and, unless I ever get into reloading .50 BMG, that's more than enough for me to measure powder charges with.
Simple fact is the larger the range is that a scale can measure, the higher the costs are in producing and manufacturing the scale are because it requires more inspection and QC. It's easy to make a scale with a 100 grain capacity accurate than it does a 500 grain capacity scale.
I do have a Hornady beam scale and it cost $70 and while it works fine, I feel the thing isn't worth more than $25.
