If you were only using Artifice to make new hilts and you were going broke doing so, you were doing something extremely wrong. Be happy with blues, RE-ing to purple is too high a cost vs. the reward.
Actually if you're broke at all getting to 400, you're not doing it right. I was able to keep myself, companions and an alt supplied with hilts, enhancements and shields and always had 6 figures in the bank.
