Thanks DS,
I agree with you. On the other hand this is one-time investment and my experience shows me that doing it myself might be
Cheaper but the time and effort to make along with raw materials will not justify the saving.
The question is: Is it that good ie. Light and comfortable. If yes, then so be it....
If no, then I will keep on searching...

Same message I wrote at 3D forum and I got a reply with a link to another tray which is $64 + shipping = ~ $70
So I see that the range is about 70-100 so if I choose to buy at list I want to ensure it is good.

Thanks
Amram
