Whenever you get a answer that says it is good and an answer that says it is not, then the answer to your question is that you need to try it yourself to see.
That is what I recommend you do. Buy a used BV and try it out. If it does not work for you, you can sell it and recoup almost all of your money.
If you like it you can then make the decision as to whether you would like to upgrade of invest more, but for planetary viewing, even inexpensive binoviewers work quite well..
There is a abundance of used gear out there that make experimenting like this financially risk free.
