English to Chinese Marketing Business/Commerce (general) Marketing

Context:

In the world of appliances, there tends to be a lot of 【"umming and ahhing"】, which is not just referring to the noise that these gadgets tend to make. Manufacturers are undecided about how best to sell higher quality and more technically advanced appliances at lower prices. As with most products, the small nuts and bolts make a huge difference when it comes to the final result and appliances are no exception.

这是一家机电元件生产商产品宣传资料中的一小段。

这里的“umming and ahhing”是指声音，还是有什么其它意思？我似乎见过有人说过“umming”和“ahhing”的本意思就指“恩”、“恩”、“啊”、“啊”之类的象声词，组合起来经常也可以引申为有犹豫不决的意思。

但这里看起来又不像这么简单或直接。在这里应该如何翻译比较好？

非常感谢！
