Yeah, 3d modeling is a time consuming bitch, and nothing looks good unless you build it yourself from scratch because 90% of the pre-supplied models kinda suck. :\
I did these a long while back:
See? They're ok, but they'll never be awesome like 3d art should be because the real stuff is probably done from scratch.
These are old, though. Like 3 or 4 years old. So maybe 3d art has improved since then, or maybe I just didn't know what I was doing. Who knows?
