I doubt it will make much difference performance wise but I suspect it will be a lower grade of plastic that wont last as long and be more suseptable to cracks and damage.....but who makes a cheaper clone??.....and how much cheaper is it? Been looking for one for a while. Might just make one up from bits for other models I can pick up off Ebay!
If you can't fix it with a hammer, you've got yourself an electrical problem!
