Quoted from markmon:Joey does not make most his mods so if you buy the same mid elsewhere it's likely the same thing
I think that's the rub here. When I see the same mod somewhere else, PDI is higher. For example:
PDI
Tron - Chrome Jet Bumper Cap Ultimate Upgrade Kit
$157.98 Shipped
Ebay
Stern Tron pinball machine mod New design pop bumper caps upgrade Chrome
$109.95 Shipped
That's not a trivial difference.
