Jeepgeek, come out with Exocaged and I one day. I have a RTR Wraith that you can test drive. Both Joe and I have the Venom Creeper.
I also had to think about what my first crawler would be. I choose the Wraith because I felt it had all of things I wanted (some speed, crawl, and neat looks.) The Rubicon was on my shortlist, but in the end, I wanted that extra bit of speed I could call upon for my Wraith. I love my Wraith!
Hobbyworld is that store you drove past. They don't normally carry crawlers (or scalers) but will happily order one for you. They are reasonable with costs. Hobbyworld probably won't beat an internet price (I am generally happy with the price I get on something), but they will take care of you if you have problems. My first Wraith had ESC problems. I brought it in, they tried to bind it, and when it did not work, ordered a new one for me. Three days later I swapped out my bad one with the new one.
RC Outlet is out by NAS Jacksonville (6800 Roosevelt Blvd). They don't carry Losi, Axial, and a couple of other brands (The Horizon stuff). They will have most stuff you need in stock. They will also treat you good. I tend to try and split my business between the two. RC Outlet has more car guys on staff than Hobbyworld, who tends to have more of the Airplane people. I don't think either store will make you unhappy.
Hobbyworld does have an on-road track in the back, but I don't think it is used anymore. I never see anyone back there. I suppose if a bunch of us tried to build a crawler course, they might let us use the space.
Go Hard Racing is a short course track in Green Cove Springs, the owner does it part time, so he is mostly open on the weekends. He does have a crawler section out there, but the course has fallen into hard times (did not appear to be used anymore). I like the track, but because I work nights, it is too far of a ride for me to use a lot.
