Well, for me, i'm the one who's afraid of those shops with too good service and autitude. Almost kena by a black shop when i was scouting for the price of the d5000 before it came out in sg. My first cam btw, and since i'm also a computer guy, i have the habit of scouting before buying.
Too good service, good price, but ended up offering $2+k for a d90 body without batteries and stuff. Ended up going to AP, with a bit of KB autitude at first. But after i really show that i'm buying a camera, they don give KB autitude le, ended up giving advice and stuff after buying my d5000 kit.
Thus, shops that survive even with bad service means their shop got rep with good price. Remember, not all good things are good and not all bad things are bad.
