LS/Vtec vs. b18c1 vs. NA b18a?? HELP!!

Ok… here i am again… I was opting for the LS/Vtec but now I don’t know… Im not that mechanically inclined to perform an LS/Vtec and don;t know of any shops around here that would do it respectably… so now im thinking of the b18c1 and MAYBE… just a thought in the back of my head… NA b18a?? What do you think a mildly built b18a would do power wise vs. a b18c or LS/Vtec?? Also cost wise vs. all 3…
Please help me out with any info!!
