Couldn't really recommend a brand of clones, but I can recommend a retailer.
Try Diamond Tour Golf in the States. They built my new clubs (not clones) for me and did a really excellent job. They have a pretty good selection of club heads and a huge selection of shafts and grips.
Their qiality is very high and their customer service is EXCELLENT.
2 Examples:
When they sent me my new set, they forgot to include the driver headcover. When I emailed them about this, they sent the headcover the same day PLUS a FREE gap wedge (same brand, same shaft, same grip as the wedges I bought from them).
I had my clubs made with Winn grips. I noticed some early wear on the grips and told Winn about this, also told Diamond Tour, who, even though it wasn't their fault, immediately offered me a full set of new grips at no charge. Still waiting to hear from Winn though !!!
