Generally with this type of thing if there is a 10-20% price difference on a stand it will be due to either the material used in manufacture - steel vs. stainless vs. chrome-plated - the way it is manufactured - castings vs. welds and machining - what is added vs. what is taken away, an additional component on a stand, etc...it really is worth it to find out, especially for the context in which the equipment will be used. 20% is a big variable.
Matthews people are proud of the products and I think that is a good thing.
My motto, however, is when you buy gear you always have to get what you want. This is a life motto, by the way! :) If that is American or Modern, then that's great. Of course Matthews wants the opportunity to get the business as does anyone else, but ultimately like I said its about testing it to see what you like and then buying based on that. You'll get what you pay for. And if you don't, go back to the manufacturer to figure out why because with the cost of some of this stuff you're owed it, know what I mean? That goes for Matthews as much as Modern, Norms, American, what have you - I'm speaking as a consumer here.
You probably did get an email from me, I designed the website and occasionally answer questions.
