Yeah, complement the welder with a hand tubing bender (like a JD2, now marketed under a different name I can't remember) and a simple, cheap tubing notcher and use your imagination! Fabbing cool safety accessories and such is really quite easy and in most cases you can have the satisfaction of designing the stuff yourself, just figure out how you want to attach a given part, fab the mounting points, and connect the dots. Just make sure you learn how to make strong, safe welds (you may already be an expert, but I don't know) before betting your melon on a rollcage or winch mount bumper.
