I'd like to make you aware of the discussion that has been going on for couple of weeks on this very topic at Racer University:
http://raceruniversity.com/campus/vi...hp?f=100&t=323
Racer University requires paid membership, so if you are not a member you may not be able to view the thread, but the conclusion is basically "the best product depends on your needs." Of course, the discussion goes into a lot of details on which features are more useful and which product does what best, etc. But at the end, for amateur racing or DE drivers, there is no one product that does it all for <$3K, which I of course agree. Posters on that thread are people that really know, have experience professionally and provide information that is beneficial; however, if you read all of the 4 pages (thus far) you may get even more confused than before. So, still take it with a grain of salt.
Thanks,
