small greenhouse kits

[shireen]

Hi gardeners,

i'm thinking of getting a small greenhouse to overwinter some plants. There are some kits available online but the most frequent complaint I hear about them is difficult assembly. I need to do this myself, so I'm a bit concerned about whether i can handle it.

Has anyone does this before?

Some of the options I'm considering, and I'm interested in other recommendations.
