You will enjoy the 3301. I have one myself (picked it up last summer). I am sure at some point you may have questions about the the whole regen and it couldn't be simpler. My first one came at 20 hours (which I attributted to the low idling during set up) and every regen since then has come pretty predictably at 31-32 hours.
I must warn you though, you will end up finding more projects just to get seat time.
