Quoted from rubberducks:Well Roman's stuff is being imported from Europe in small amounts, and it is made in small batches in Germany, to a specific spec ... which is quite costly. But PDI sell it for $295 (as they always have), and Nitro sell it for $225. So one of those two is making a pretty big margin.
AFAIK both Stern and JJP's glass is just standard stuff from presumably large OEMs (whatever is cheapest), made in huge bulk. So they should be making a fortune on it.
There's MUCH cheaper stuff available in Europe ... which in good lighting conditions (few reflections overhead) is even better than Roman's (due to lack of tint), but not quite as good in non-ideal circumstances - in either though, miles better than Stern or JJP's product.
I have both PDI and Invisiglass. Both are great products. With delivery PDI is $40 ($370 versus $330) more so I typically go with Invisiglass. At least in my game room environment the glass makes a big difference.
