I have noticed that patience is the key with retrimmed auctions. The 3 spoke above for instance (3'rd pic from the top) was recently sold for just a 121 euro's which is reasonable imo:

On the other hand they can also be ridiculous expensive when not offering an old wheel to retrim:

Another option is to make a nice deal with you local retrimmer with an old wornout bargain or do what i did and be happy with a second hand original in good condition
