Ask for a photo before buying parts from this supplier (Bulgaria I think). My experience was mostly good, but Stargate ball guide part I bought was not as described (it was repaired by a welder). I haven't asked for compensation, it was my own fault for not asking for a photo, but I thought I'd warn other members to be more cautious than I was.
Update: Seller kindly offered to refund me cost of part without requesting return, but I am keeping part as a backup so have declined the refund .
