Oh wow, we must have been really lucky then. We had 3-4x 8W heads year ago and they were all great.

My opinion... don't cheap out on a PBS... 20W is a huge amount of power, and a few percent loss in any cube is quite a lot of thermal energy. Do you trust the glue that's holding the glass together!
A cheap one may work, but for how long? This might just be me being over cautious though
Good quality standard PBS from a known manufactuer with proper testing + damage threshold data:

Higher power PBS cubes (probably overkill for your needs!):

Both of those cube type do not use glue and are optically contacted.

I don't have an email address to hand, but the contact we dealt with was Frank Wang.
