Hi Waqas,
I have used both suppliers numerous times. There just doesn't seem to be the "ease of use" or a print catalogue geared towards the restorer. Prices are usually not included, and if they are included, they are usually not accurate. Also, there isn't a large availability of quality, reproduction parts yet. For example, a lot of our chrome or stainless trim parts are through the roof, if you can find them. They are not available in reproduction.
