Not sure why there would be a suggention to buy the VRF subc, and not the 904L ARF w/yuki or "sh3135v2" from Puretime. Mine is pretty close to perfect. I went ahead and dropped a gen 3135 (w/blue parachrome HS, and free float balance wheel) and Dial. Local AD did full inspection and never even suggested or hinted of suspicion that there wasor may be a problem? Total investment $2650. Throw in a additional $140 for box and custom papers and you're set. Just maintain your scruples and dont succumb to the urge to see what you can get on eBay - at some point you would get caught, especially if it became a habit after making 5K a pop profit 😉
