Searching for Small Greenhouse Options

I am having a dilemma.  I decided that I do not want, nor have the space for, a full-fledged greenhouse.  But what I would like is a small, patio sized one.  Something that I can continue to grow lettuce and whatnot in during the winter.  The ones online that people have made out of old windows are pretty, but I've decided against that route.  I want something small, simple and ready to assemble.

I have seen some interesting options.  I thought this Patio Grow House seemed nice, but the few reviews I could find were mixed.  I'm not factoring in the comments on any of these that involve them being light.  My overly cautious husband weighs everything down like we live in a tornado prone area.  It's a good thing, because I never think to do it.

 

Then I came across this Grow Station which seemed maybe better durability-wise.  The description does say cold frame, but I have to say, it looks more like a greenhouse to me.

 

 

Then I came across these Lean-to Greenhouses but I can't really find anything in terms of reviews.  Plus I hate ordering stuff online at places I don't know.  And I like when they have actual storefronts to return stuff to.

 

 

 

This one at Lowes is definitely the cheapest option, but I'm not crazy about the plastic. I rather spend more and not have to replace it every year. But at $40, it is tempting....

 

 

This one from Home Depot looks like it could be perfect, but of course it's online only and they're out of stock.  Yeeesh.

 

 

In the meantime, I have my seeds staring in the Burpee Seed Starting 72 Cell Greenhouse Kit.  I used to be very DIY with the seed starting.  I tried making those newspaper cups...they just got moldy and gross.  I used plastic cups, that was kinda okay, but kinda a pain.  I tried this out last year, and holy guacamole, so much easier.  You can buy just those weird expanding pellets and reuse the trays every year.  Or for around $8 be not very green and do what I did and just buy a whole new one.  I'll keep you posted on the greenhouse search.
