If you are worried about cost and have some extra time/creativity try you hand at scratch building. It's cheaper, far more satisfing, and you can literally do what you want. Templates can be found all over the web for just about any vehicle, I have most that you can find. I've been scratch building a Hellblade, it's not that hard and you can find most of the materials either around you house or at WalMart. There are a few specialty plastic peices you'll have to buy. I think all together I've spent about 20$ and 40 hours so far.
