Thankfully we have the internet.
It is a shame, but many sales people are just so ignorant they drive you out of the store and literally force you to buy anonymously over the net.
I usually do a lot of research, talk with others, and try to make up my mind as to what make/model/etc. so that by the time I hit the store it really comes down to price. I have found that within certain categories (for instance, the table saw you mentioned) that they are all of high quality and will provide years of service) you can't make a 'bad' decision. I often use the FWW product reviews to narrow the field, and I have personally found them to be quite compatible with my own personal proclivities. If the store can't/won't offer a compelling price, I move along. Even when their pricing is out of whack with the 'net', I will ask them to match it; if they won't come close, I move along. I have to say, and this is not a plug for them, but my local Woodcraft store is great to deal with, has quality suggestions, does not try to sell me crap I don't want/need, and makes the whole experience a positive event with good pricing. As a result, I go out of my way to patronize them.
Now...about the brakes, etc. on the table saw....I have an old Craftsman with the blade guard removed, no splitter, and no brake. I bought it used, and when the time comes, I expect to sell it used. Does the salesman out there pushing the 'you can't sell that saw because it has no brake' have any idea how many millions of saws which are out there, like mine, that have NO safety features whatsoever? I doubt it....but it is a good 'sales' pitch for some idjit who swallows it hook, line and sinker.
BTW, I still have all my fingers.....
