I am working on converting a roland fj 50 and fj 40. I'm getting the parts to convert them to run solvent inks. just got them on new year's. i like these particular models. they may not be the fastest but they are inexpensive to maintain compared to their modern counterparts. dx-2 heads are way cheaper than say dx4 or 5 heads. hope this helps. feel free to ask any questions. -Bob
