So far, I have the one failed model, but realise that the cost of this one failed model is maybe $20. I guess it’s my fault for not noticing the prohibitive prices of replacement resin (US$100 for 500ml), but it does rather make it severely unattractive to do much experimentation. I am not going to beef about being tied to Uniz own-brand resin, but I wonder whether someone from Uniz could comment on whether the cost of resin is ever going to come down, or if replacement resin will always be so expensive as to drain all the fun out of experimentation?
