I’ve been using the AE8 preview for about a month now. This is a HUGE update for Intel-Mac users. AE7 ran like crap on Intel Macs. Multiprocessor support is also huge. RAM previews and renders are super-fast. As for cost there aren’t too many professional quality products out there that you’d deem ‘affordable’. Other than Shake ($499 or so) which has been discontinued, I can’t think of anything comparable that is less than AE’s $999, or $299 upgrade if you are a current user which it sounds like you are. If you are a student they offer all of their products at a decent discount. For the features that you get at it’s price, AE is probably the best value out there.
