Hey guys, I need soms help with RGB dichroic mirrors.

I have done some research and found out the dichroic on o-like which are pretty cheap but have a hefty shipping charge with them because I live in the UK. I have also heard some bad reviews on them but might not apply to these sets of mirrors.

Do you guys have any better deals for me? Paying £28 including shipping for a tiny set of mirrors seem expensive. I live in the UK so I would appreciate if you found some mirrors which are sold at good prices or if this is infact a good deal and go order it.

I plan to create a tunable RGB laser which you can use to create different colours of beams. Just like JLSE creates but in a less compact form becauss I am not master like him
