Hi Tom, how nice of you to pop in.
I was always leery of the Canadian ones with no dome. I was happy enough with the deep Haxnicks one that I used last year to just recently buy another- the compact one from Gardener's Supply, made by Haxnicks.

I've always found Gardener's Supply to be a reputable company.
I just seeded the new compact one a couple of days ago and plan to use the deep one from last year for impatiens again. They're in fine shape for reuse.
