Advice as into what???? I guess it depends are you just going to be bashing, are youo going to do comps... are you look for a scaler (realistic crawler)
It's hard to give advice without knowing more information.
I had a Venom Creeper for 2yrs and loved that crawler. I comped with it pretty much every Tuesday night and crawled/bashed around on weekend at the local rocks/river beds in the area. The Creeper was the best value for the money, $125 for just the roller was a great deal cause then I could buy my own electronics for it.
It flexed like crazy as well and worked great with the added dig unit as well for comps. If you want search on Youtube for "snwchris" and you'll see some of my Creeper videos and how well it performed.
