What barlow lens will work with my Heritage 130p telescope?

[Lotinsh]

I recently got my telescope (130p) the views are amazing, but I ran into a problem, my 3x barlow lens wont focus and it seems others have similar issue and I need short barlow lens for this telescope.

Can anyone with this telescope recommend me some barlow lens that will work on the 130p? Thanks.

Yes, I think the 3x was recommended more for imaging.

This one is often recommended as a low-price model.

I have this one and get on well with it. It comes apart to give two different magnifications (provided the back of the eyepiece can accommodate it).  Some other barlows can also do this.
