It is expensive but worth it IMO. Even with dim ambient lighting I think there is room for improvement and it will make a difference that other MacGyver fixes won't. As RGV said once you run out of space the only thing left to do to pins is pimp them up a bit. On the whole most mods don't float my boat, I tend to like upgrades that enhance what is already there but don't add things that shouldn't be unless its an obvious omission. Bolting on expensive plastic Robbie Robots and the like just look tacky IMO and don't seem to serve much purpose other than blocking your view of the ball! The only real exception to this rule in my collection is the lit T1000 from
@Judge Dreads.
Some of my pins I don't ever intend to sell like TZ for example. Its typically one of the most heavily modified machines going and also IMO the greatest pinball ever made, and ever likely to be made (there just isn't the money in pinball that there was back in 1993 so no designer will be let loose like Lawlor was then.) I have a lovely example with original unfaded cabinet, really nice original playfield etc. Mods wise it has upgraded Pinball Pro speakers, reinforced clock and slot targets, reinforced slot machine weldment, cliffys all round, the missing flashers under the door, lit gumball machine with coloured gumballs and tastefully done LED lighting. (No coloured lamps under white inserts or themed GI for me, just nice bright original coloured inserts and white GI.) To me anti-reflective glass is one of the only ways left to improve it further and show off the beauty that lies beneath. People spend £300+ on Colour DMDs that you hardly ever look at because they're cool (myself included,) when 99% of the time you are looking through the playfield glass. When I consider it this way the glass starts to look good value for money!
I'm going to keep the scratch free sheets of standard glass and put them back in any pins I decide to sell in the future, allowing me to rotate the PDI in to whatever takes its place. So its a bit of an investment in improving pinball pleasure for many years to come.
Slight tangent but anybody who hasn't seen or tried the Optix Maximus GI lamps from Comet Pinball, I recommend you check them out, even if you aren't normally a fan of LEDs.
http://www.cometpinball.com/category-s/1836.htm The sunlight ones in particular look incredible. I've tried a lot of different lamps and their claims of being the best GI lamp period are well founded, the photos just don't do them justice at all. Lovely and bright without hurting your eyes, lovely colour and most importantly awesome dispersion. They allow you to see the ball perfectly when playing in the dark and bring out the colours of the artwork instead of turning everything orange like incandescents do or harsh clinical white like most LEDs.
