Sorry to jump in but I think the one Zeeb is talking about is different than the one you are asking about. The one you are asking about is 1.9 meter version which is new. The one Zeeb is talking about is the original version which I believe was slightly larger. (maybe 2.1 or 2.2 meter). if you search you will find the thread for that one which if I recall correctly was started by Dr. Scoles.
