Well, after a looong 6 week wait my Chupacabra 50 just arrived! I shipped from Malaysia tuesday and got here friday, unbelievable. I haven't tried it yet but sure will tonight and over the weekend. I'll let you know the good and bad. From what we have seen so far the build quality is excellent, except for a "Ruby" tube. Once I break it in and get used to it, then I'll try some other tubes. Time will tell.
