I borrowed one from my father, it was 16.5 x 18.5 inches.  By using it with
a 20" monitor, you will have as big as 30" screen !!!  I was so exciting :)
Anyway, you have to accept some 'not good' effect on the edges... only a
minor thing which can be neglected.  It's worth :)  Be sure to have enough
distance between you, the FL, and the monitor.

IMHO, in my case, it was a major improvement and I got it from there
http://www.optelec.com/ProductDisplay.asp?ProductID=140 and yes it's worth
the investment
