They are not all the same. LRP is smoother than a Tekin by a tick, BUT NOBODY HAS CUSTOMER SERVICE LIKE TEKIN!!! If you have a problem with it you are going to have a working one in your mailbox in about a week. With the others.....when they get tired of you calling them after about 4 weeks they will "try to get it out this week" (being the 5th week) I would take my hundred that I have budgeted, throw it in a jar, and drop twenty a week in there until I had enough to get a Tekin.
