Help Please!

As the days tick down until we settle on the new house (next Friday!!), I've started looking into all the "stuff" we need to buy. My current obsession...window coverings for our 2 sliding glass doors. Both our living room and basement have sliding glass doors out to the deck and yard.

Right now they both look like this...

Only without the ugly 80's furniture. But you get the idea. Two huge bare glass doors.

The main problem is that our house is on the corner, so I'm majorly worried about privacy. I feel like any cars that drive by will get a perfect view into our living room. Eventually, we would love to replace both doors with doors like this:

Lovely framed french doors. But unfortunately, after we looked at doors at Home Depot and pretty much had a heart attack over the price, we realized this is quite a ways off.

So we will have to make due and find some nice curtains/blinds/etc. to use in the meantime. My question is, are there any options besides these? The dreaded vertical blinds!

I know they make "nice" vertical blinds, but I didn't know if there was something else that would provide a good amount of privacy and still look nice. We will be using both doors quite a bit, as that's the way we will let Spencer out into the yard, so I don't want anything super hard to manage or like big bulky curtains I'm constantly having to open. But I do want something that lets a lot of light into the room. Also, budget is somewhat of an issue, so probably nothing that has to be custom made or anything like that.

So any help or advice would be majorly appreciated. Even if it's to tell me that vertical blinds are the way to go. Thanks!!!
