If those are your only reasons,
1. Yeah the power supply fan sucks but with a exhaust fan mod, it cuts the high RPM fan noise down significantly.
2. I will mail you two old bulb flashers for every one of your Stern flashers. That way when the old flasher burns out you will have a spare.
3. Really, really, REALLY? The power switch is why you think the spike system sucks. Tell ya what, I got a selfie stick some one gave me, I will regift it to you, that way you can reach the switch.

Now 4 or five years down the road when one of your led display boards goes bad under the play field and you have to pay an arm and a leg to replace it, then YES the system components suck in the case that if one small led goes bad your average joe is not going to be able to micro solder that off and replace it and end up buying the whole led display.
