The $4k extra, you think is worth it?

Over TriState, Alpha and Royals? Yes and I am not even sure who makes those windows.

Who makes alpha windows and who makes Royal? the okna pricing looks good.

what state are you in?

The Okna price might be considered high if they are just inserts with no thrills. Window brands can be very regional so a lot of can’t truly evaluate all of them. Consider other brands such as Soft-Lite , Sunrise ,Polaris or let is know what else you have Available. You want to compare brands that are quality , vet the company installing them and make sure the installation details are the same.

I'm on Long Island n NY. Alpha and Royal make they're own windows. Saw the Royal today. For 20K I could get their new builds, but I really don't like the window.

I found one place that offers Soft Lites, Ideal, Hi Mark & Polaris. I'm going to try to get there soon! I think a couple of these are a level above the Okna 500's?

The 500 is their more entry level product. If you are going to compare upper lines, you should make the same model comparison across products (i.e. Soft Like Element = Okna Envirostar in terms of the comparative).

+1. Solid price for the okna model, but their higher lines are even better. The HiMark that you mentioned is an Okna product as well.

Regarding the worry about the installer, if he goes under another Okna dealer will simply be your go-to. Contrary to what you may have thought, an arrangement like that offers you more security as a consumer than a smaller manufacturer/installation combined company. Sure you might have to pay a fee for service parts to be installed in that unfortunate event, but that is certainly better than the entire company going away making parts unavailable.

Thank you all for your responses!
