I need new tires, and am wondering about changing the valve stems. In another thread, someone recommended these:

However, when I brought in my Suzuki Burgman super-scooter's wheels in for tire replacements a number of years ago, I brought in a pair of 90-deg. metal stems and the shop recommended against them, saying that they didn't seal well or could leak or something like that, and recommended regular rubber valve stems. (Not that I should necessarily take what that shop says, because they replaced my original stubby ATV-style valve stem with a standard one, making the 14" rear tire even more difficult to air up!)
Any comments pro or con on this? I really would like the 90-degree ones if they were reliable.
I'm also on the fence about whether I attempt to change my own tires, or bring the wheels in to a shop to have them do it. It's $45ea to replace and balance when I bring in my own tire, $35 if I buy from them. Given that I would need to buy tire levers and rim protectors, the cost of 1 tire set change is a wash in the near term. I don't know if I'm better off having a shop do it so that I don't scratch my rims. Any thoughts (well, most any thoughts) appreciated.
