I have Cointaker Premium Frosteds in my WCS and the Comet Sunlights in my OXO, love them both! My BSD came in with some now older LEDs (i.e., no flexies anywhere) that are OK but I'm sure could be improved... someday.
Went with Pinsider Astropin's config on my STTNG backbox (love it!) but still haven't attempted the playfield on my STTNG... too daunted by all the possibilities and almost sure I'll be disappointed in any kit.
