The best RCM in this price range is to make your own. This can be done for under $100 and will work as good if not better than the commercial RDM's in this price range. If this is not an option for you then I'd say pick up a VPI 16.5. The VPI 17 is not, IMO, worth the money. Another option is to save up some more until you can get a Loricraft.
