You can reply/post to existing threads there without reaching Level 2. You only need to be Trust Level 2 to start NEW threads there, and your question isn’t really warranting a thread of its own (this isn’t Reddit etc.) anyway, so it’d get moved to the general thread.
Thus, the best place to post your question(s) is in this (General Purchase Advice) thread, anyway, rather than starting a new, super-specific one (that very few people will likely read).
