Got them from a wheel wholesaler (best friend for 20 yrs), so my cost is NOT a fair comparison.
The only visible difference is the lack of a BMW part # in the barrel of the wheel and the lack of the "M" rectangular knock-out area (where the M logo would be). Look for a local place that does a lot of tuner jobs and stays busy. Try to find a shop with a "force" balancer - a system that simulates road force (load) on the tires as they spin on the balancing machine, you'll get a much truer balance than plain static weights, and you shouldn't have to re-balance for a while. Any wheel shop should be able to order as a wholesaler from the replica companies. I don't remember the latest hungry supplier, but I know that Voxxwheel has my style as well in chrome, and even has replicas of the newer m5 and e46 m3 wheels. Their www has a section for dealers, and they love to have new dealers order from them.
Also remember: you will potentially pay less than half of OEM retail, so don't give the wheel shop a hard time about possibly spending $120 or more to mount and balance. Treat them well (like you'd like to be treated) and they will take care of you in the future. (My own personal experience). AND: they should also be able to get you pretty good deals on tires through the wholesale distributors they go through (i.e. the Mastercrafts on my 5 are made by Cooper tire, cost WAY less than name brands, and have really good handling and roadwear.)
NOTE: I do not sell wheels, nor am I endorsing any specific vendor, I just like saving a buck when I can and feel if anyone else can through guidance, more power to them. Besides, if you don't need the nameplate, anyone can save half off retail cost to spend on other car goodies!
