On which site should I consider posting my question?

None. Shopping questions are off-topic throughout the Stack Exchange network.

Do note that the Stack Exchange system powers Q&A sites, not "forums". That's probably the source of your confusion. Questions here need to be specific, answerable, and useful to other people. If you can imagine people having a long discussion about your question, or that there are multiple correct answers to your question, then it's probably not a good fit around here. All of this is discussed in the FAQ for each site; for example, the Stack Overflow FAQ. I do recommend that you read it.
