Ordered the MFS 2000 rails, now have the complete system. I haven't needed this size yet but as I have used all the other sizes, I figure it's just a matter of time. I know these have gotten somewhat of a bad rap, as long as care is taken during assembly and adjustment, they are great. I bought two sets from Amazon Warehouse, both were advertised as new, but both had some damage. Amazon discounted the cost on the first set, but would not on the second. I work with aluminum all the time so I kept and repaired both as I was not going to full price for them.
