Well, I got mine from Island-4x4. I used to recommend them to everyone but then I had to send back a faulty part and ended up having to threaten legal action before my money was refunded. No communication at all. Pity as until then they'd always been great.
Always worth checking Rimmer Bros. Sometimes they surprise you. Actually, they always surprise but occasionally it is a nice one where they are cheaper. Dingocroft are similar.
Used Paddock Spares with no issues. And another place whose name I always forget, something like the Big Four.
