I recently used the place that my boss uses to get his supplies.. CAM tattoo supply, and let me tell you they are great!! I payed $10 for C.O.D. and my order was there in 2 days.. No joke! Their needles are top knotch and they carry every brand u can think of.. They also sell Intenze ink in 1/2 ounce bottles witch is very hard to find. I am not by any means trying to advertise for them but every penny counts when you are starting out and they are very reasonable.
Cam Tattoo Supply Company ships worldwide, and they make good supplies. Machines are different. You want to buy from a reputable machine builder. I recommend irons made by Jim Martini and Aaron Cain, both superb machine builders in the UK.
