yes, i understand about buy now, get screwed later
however, version one is 50% right now. i dont know FF inc.'s official policy on all this, so i would see if there is a related question on their forums or in their help section or just in their sales area. and, push come to shove, just log into the forums and ask vladimir. he's busy a lot but he does respond more than a lot of companies that have forum presences.
i also dont know when version II will be officially released. i hinted on their forum that i would expect it out no later than mid-summer and i got one response from one of the FF guys that that was probably longer than they were expecting it to take. so, there's some data, anyways.
also, in version I, their 30 demo could be extended to 90 days... in some cases. this was usually if the person requesting the extension was active and visible on the web site. i dont know if this is still done or not, but it never hurts to ask. and in 90 days, one could conceivably earn enough high usage filters to get the program for free
