@John (bowlesj), I'd be interested in hearing how this works out for you. I've been considering purchasing BIAB for at least a couple of months and, like you, would prefer to download a trial first. I have been reluctant to purchase since I truly do not know if I'll be satisfied with the results I get from the program. And in my case I'm pretty sure I would need the $500 package so its not a trivial amount to spend without being sure!

Side note regarding a trial...I'm pretty sure they used to offer one but I'd bet the main reason they eliminated it was due to piracy concerns. Most trials are just the full version that can be activated with a key and 10 minutes after you release such a trial the pirates will begin posting keys and cracks. I doubt size has much to do with it as you wouldn't need to provide many RealTracks with a trial and there are plenty of product trials you can download that are very large!
