I use Udimi often and am glad to recommend the seller's names that I have gotten great results from! One of the sellers I would recommend is Heather Alessandra. This was actually my first solo ad from Udimi for MWK and got excellent results so I continued to order more from her. I have also used Dan Fairaday and Sally Fields. One thing about Udimi that is unique when purchasing solo ads is you can search buyers by sales, ratings or niche. Udimi is one of the very few programs I recommend highly.
