Should i upgrade?

[Shadow350Z]

Ok so as the title says but as to what?...
I have not been into the RC scene for a while now... like 3 years to be exact.

What i have at my disposal is the newer version of the E-maxx. When i was more into the hobby, I made the E-maxx to be able to tolerate the punishment of a brushless set-up (Novak HV4400) with aluminum upgrades and many drivetrain upgrades thanks to RC-monster.

I was wondering if I should upgrade to a more updated chassis like the E-Revo and if i should sell the E-maxx as a roller and use the Novak Brushless and put that into the brushed E-Revo. I can also sell the whole chassis with the Brushless and get the Brushless Kit Revo.

Also i got no idea on the prices for my E-maxx.
Please help. Thank you in advance!
