I've bought stainless lines for my 51 AD from Inline and lines for my 50 from Classic Tubing. They both were excellent products and I'd buy from either again, though I'd probably go with Inline. Just little things,like having the ends of the lines capped and a little better box would make me tend to go Inline. Like Olblue said,they had to bend the long line to the rear in half for shipping.
