yeah, it really does all depend on what you are doing. I know youre pretty regular on here, but what kinda engine, (i assume whatever engine you have is in a del sol), what kind of power goals, na/turbo, usual driving habbits for the vehicle?
all are good things to know. i know most people say that Rocket Motorsports has really good cams, but i havent checked them out yet. also, if you go with rocket, then you have to use their valvetrain (well you dont have to, but they wont sell you JUST the cams, so you might as well use theirs).
My bet would be that your engine builder is probably a distributor for crower. if thats the case, he can sell you their cams at retail and pocket the money from the w/h price difference.
