Tak FS128 vs TOA130 vs AP130 f/6

I am on the notification list for an AP130 f/6. A long wait to come. I currently have a Tak FS102. I want to move to a 5". How does the FS128 compare to the TOA130. I know the stats, and there is one more piece of glass, but is the price and weight worth the difference? In the very near future I will purchase one or the other, is the TOA that much better?
And finally, does anyone have a comment about the comparison between the TOA130 vs the AP130 f/6?

Thanks, Steve

How long a wait do you have several month's or several years. Personally I opt for the AP 130 F6 I own one and I love the wide field views it gives with my 31 Nagler I've had my scope since 1996 and have compared it too many other scope including the AP 130 F8 and found no differences in rendering of Jupiter at high power. If your interest is purley visual ie planets then you might be better served with either the FS 128 my next choice or the TOA 130 which I have issues with as far as cool down times are concerned with. If your in California or Ariz where cool down is not really and issue then go for it. If your in the Midwest or back east where you can get some real extremes in temp swings esp between indoor vs outdoor temps and your a real stickler for image sharpness I would be wary and go for the FS128 instead. The slight color error that the Tak doublet introduces is very minor in my book compared to a center element that lags the interior and outer elements while coming to equilibruim. Roland Christen has experimented with these broken Apo designs and has noted some long lag times with the center element cooling properly but this was with a 6 inch sized element. Maybe its not an issue with the TOA 130 but that would be something I would be keeping in mind.
