Most dealers source from the same factories. Chances are you'll get the same watch from any of these dealers, so looking for which dealer has the "best quality" is usually impossible.
I will say that Eurotimez has had some delivery and communications issues as late, so you may want to eliminate them as a dealer for the time being.
Marvelous Replica will actually QC your watch and give you photographic evidence of the QC, which is more than most dealers do. Marvelous is by far the go-to dealer for beginners as the communications are fast. It's worth a few more bucks to have some hand-holding when you're new at this.
Bear in mind that there are both quartz and auto versions of this watch, and I believe this is one of the throw-back models where the quartz version is cheaper in both price and quality. They do not use the same crystal and I think even the dial may be different. The auto version will be a higher overall quality and more true to the gen - but I don't honestly know how "accurate" a rep the SLR is.
