The only Duratrax product I've ever owned was masking paper for painting my new body for my buggy. It got the job done =)
When I got my Storm I knew I'd love R/C. I always did when I was a young little guy with my electric nikko cars. So, I went with something with a lot of hopups and good design. I've been extremely happy with it.
If you are unsure if you are going to like the hobby, I see nothing wrong with staying safe and getting yourself a Duratrax on the cheap. A lot of people say "Duratrax sucks" but don't own any, they just heard someone else say it. I don't own one. I mean, it's likely not going to be the same quality of a much more expensive car, but if you're not crazy with it it'll probably be a lot of fun.
Make sure you can get parts for it easily, from either your LHS or an online store.
If you have friends doing R/C, look what they own. Try to get something somewhat comparable to what they drive, or it'll be no fun. ie - if they all drive street cars, get a street car.
Whatever you decide, I'm sure you'll love the hobby and you'll always be looking for to get the next best thing anyways, whether you get a Duratrax, an Ofna, a GS, or whatever. =)
